Add TenantCustomTier system and fix BusinessEditModal feature loading

Backend:
- Add TenantCustomTier model for per-tenant feature overrides
- Update EntitlementService to check custom tier before plan features
- Add custom_tier action on TenantViewSet (GET/PUT/DELETE)
- Add Celery task for grace period management (30-day expiry)

Frontend:
- Add DynamicFeaturesEditor component for dynamic feature management
- Fix BusinessEditModal to load features from plan defaults when no custom tier
- Update limits (max_users, max_resources, etc.) to use featureValues
- Remove outdated canonical feature check from FeaturePicker (removes warning icons)
- Add useBillingPlans hook for accessing billing system data
- Add custom tier API functions to platform.ts

Features now follow consistent rules:
- Load from plan defaults when no custom tier exists
- Load from custom tier when one exists
- Reset to plan defaults when plan changes
- Save to custom tier on edit

+# SmoothSchedule Billing & Plans System
+
+This document describes the architecture and capabilities of the billing and subscription management system.
+
+## Overview
+
+The billing system supports:
+- **Plans with Versioning** - Grandfathering existing subscribers when prices change
+- **Feature-Based Entitlements** - Boolean (on/off) and integer (limits) features
+- **Add-On Products** - Purchasable extras that extend plan capabilities
+- **Manual Overrides** - Per-tenant entitlement grants for support/promos
+- **Immutable Invoices** - Snapshot-based billing records
+
+## Seeding the Catalog
+
+```bash
+# Seed/update the catalog (idempotent)
+docker compose -f docker-compose.local.yml exec django python manage.py billing_seed_catalog
+
+# Drop existing and reseed (for fresh start)
+docker compose -f docker-compose.local.yml exec django python manage.py billing_seed_catalog --drop-existing
+```
+
+---
+
+## Current Plan Catalog

+```
+
+## Core Models
+
+### Plan
+
+Logical grouping representing a tier (e.g., Free, Starter, Pro, Enterprise).
+
+```python
+Plan:
+    code: str           # Unique identifier (e.g., "pro")
+    name: str           # Display name (e.g., "Pro")
+    description: str    # Marketing description
+    display_order: int  # Sort order in UI
+    is_active: bool     # Available for new signups
+```
+
+### PlanVersion
+
+A specific version of a plan with pricing and features. Enables grandfathering.
+
+```python
+PlanVersion:
+    plan: FK(Plan)
+    version: int                        # Auto-incremented per plan
+    name: str                           # "Pro Plan v2"
+
+    # Availability
+    is_public: bool                     # Visible in catalog
+    is_legacy: bool                     # Hidden from new signups (grandfathered)
+    starts_at: datetime                 # Optional availability window
+    ends_at: datetime
+
+    # Pricing (in cents)
+    price_monthly_cents: int            # Monthly subscription price
+    price_yearly_cents: int             # Annual subscription price
+
+    # Transaction Fees
+    transaction_fee_percent: Decimal    # Platform fee percentage
+    transaction_fee_fixed_cents: int    # Fixed fee per transaction
+
+    # Trial
+    trial_days: int                     # Free trial duration
+
+    # Communication Pricing (usage-based)
+    sms_price_per_message_cents: int
+    masked_calling_price_per_minute_cents: int
+    proxy_number_monthly_fee_cents: int
+
+    # Credit Auto-Reload Defaults
+    default_auto_reload_enabled: bool
+    default_auto_reload_threshold_cents: int
+    default_auto_reload_amount_cents: int
+
+    # Display Settings
+    is_most_popular: bool               # Highlight in pricing page
+    show_price: bool                    # Show price or "Contact us"
+    marketing_features: list            # Bullet points for pricing page
+
+    # Stripe Integration
+    stripe_product_id: str
+    stripe_price_id_monthly: str
+    stripe_price_id_yearly: str
+```
+
+**Grandfathering Flow:**
+1. Admin updates a plan version that has active subscribers
+2. System automatically:
+   - Marks old version as `is_legacy=True, is_public=False`
+   - Creates new version with updated pricing/features
+3. Existing subscribers keep their current version
+4. New subscribers get the new version
+
+### Feature
+
+Single source of truth for all capabilities and limits.
+
+```python
+Feature:
+    code: str           # Unique identifier (e.g., "sms_enabled")
+    name: str           # Display name
+    description: str    # What this feature enables
+    feature_type: str   # "boolean" or "integer"
+```
+
+**Feature Types:**
+- **Boolean**: On/off capabilities (e.g., `sms_enabled`, `api_access`)
+- **Integer**: Numeric limits (e.g., `max_users`, `max_appointments_per_month`)
+
+### PlanFeature (M2M)
+
+Links features to plan versions with their values.
+
+```python
+PlanFeature:
+    plan_version: FK(PlanVersion)
+    feature: FK(Feature)
+    bool_value: bool    # For boolean features
+    int_value: int      # For integer features
+```
+
+### Subscription
+
+Links a tenant to their plan version.
+
+```python
+Subscription:
+    business: FK(Tenant)
+    plan_version: FK(PlanVersion)
+    status: str                     # "active", "trial", "past_due", "canceled", "paused"
+    started_at: datetime
+    current_period_start: datetime
+    current_period_end: datetime
+    trial_ends_at: datetime
+    canceled_at: datetime
+    stripe_subscription_id: str
+```
+
+### AddOnProduct
+
+Purchasable extras that extend plan capabilities.
+
+```python
+AddOnProduct:
+    code: str                       # Unique identifier
+    name: str                       # Display name
+    description: str
+    price_monthly_cents: int        # Recurring price
+    price_one_time_cents: int       # One-time purchase price
+    is_active: bool
+    stripe_product_id: str
+    stripe_price_id: str
+```
+
+### SubscriptionAddOn (M2M)
+
+Links add-ons to subscriptions.
+
+```python
+SubscriptionAddOn:
+    subscription: FK(Subscription)
+    addon: FK(AddOnProduct)
+    status: str                     # "active", "canceled", "expired"
+    activated_at: datetime
+    expires_at: datetime            # For time-limited add-ons
+```
+
+### EntitlementOverride
+
+Manual per-tenant feature grants (support tickets, promos, partnerships).
+
+```python
+EntitlementOverride:
+    business: FK(Tenant)
+    feature: FK(Feature)
+    bool_value: bool
+    int_value: int
+    reason: str                     # "support_ticket", "promo", "partnership", "manual"
+    notes: str                      # Admin notes
+    granted_by: FK(User)
+    expires_at: datetime            # Optional expiration
+```
+
+## Entitlement Resolution
+
+The `EntitlementService` resolves effective entitlements with this precedence:
+
+```
+Override > Add-on > Plan
+```
+
+**Resolution Logic:**
+1. Start with plan version features
+2. Layer add-on features (add-ons can extend but not reduce)
+3. Apply manual overrides (highest priority)
+
+**API:**
+```python
+from smoothschedule.billing.services.entitlements import EntitlementService
+
+# Get all effective entitlements for a tenant
+entitlements = EntitlementService.get_effective_entitlements(tenant)
+# Returns: {"sms_enabled": True, "max_users": 25, ...}
+
+# Check a specific boolean feature
+can_use_sms = EntitlementService.has_feature(tenant, "sms_enabled")
+
+# Get a specific limit
+max_users = EntitlementService.get_limit(tenant, "max_users")
+```
+
+## Seeded Features

+    subscription: FK(Subscription)
+    period_start: datetime
+    period_end: datetime
+
+    # Snapshot values (immutable)
+    plan_code_at_billing: str
+    plan_name_at_billing: str

+    stripe_invoice_id: str
+    paid_at: datetime
+```
+
+### InvoiceLine
+```python
+InvoiceLine:
+    invoice: FK(Invoice)
