refactor: remove backward compatibility code for pre-launch baseline

Clean up accumulated backward-compat shims, deprecated wrappers, unused
aliases, and legacy code across the codebase. Since the platform is not
live yet, this establishes a clean baseline.

Changes:
- Delete deprecated middleware/context.py (RequestContext, get_request_context)
- Remove unused factory get_store_email_settings_service()
- Remove deprecated pagination_full macro, /admin/platform-homepage route
- Remove ConversationResponse, InvoiceSettings* unprefixed aliases
- Simplify celery_config.py (remove empty LEGACY_TASK_MODULES)
- Standardize billing exceptions: *Error aliases → *Exception names
- Consolidate duplicate TierNotFoundError/FeatureNotFoundError classes
- Remove deprecated is_admin_request() from Store/PlatformContextManager
- Remove is_platform_default field, MediaUploadResponse legacy flat fields
- Remove MediaItemResponse.url alias, update JS to use file_url
- Update all affected tests and documentation

## Migration from RequestContext
The previous `RequestContext` enum is deprecated. Here's the mapping:
| Old (RequestContext) | New (FrontendType) |
|---------------------|-------------------|
| `API` | Use `FrontendDetector.is_api_request()` + FrontendType |
| `ADMIN` | `FrontendType.ADMIN` |
| `STORE_DASHBOARD` | `FrontendType.STORE` |
| `SHOP` | `FrontendType.STOREFRONT` |
| `FALLBACK` | `FrontendType.PLATFORM` |
### Code Migration
**Before (deprecated):**
```python
from middleware.context import RequestContext, get_request_context
context = get_request_context(request)
if context == RequestContext.SHOP:
# Storefront logic
pass
```
**After:**
```python
from middleware.frontend_type import get_frontend_type
from app.modules.enums import FrontendType
frontend_type = get_frontend_type(request)
if frontend_type == FrontendType.STOREFRONT:
# Storefront logic
pass

## Request State

### DON'T
1. **Don't use `RequestContext`** - it's deprecated
2. **Don't duplicate path detection logic** - use FrontendDetector
3. **Don't hardcode path patterns** in middleware - they're centralized in FrontendDetector
4. **Don't check `request.state.context_type`** - use `request.state.frontend_type`

**Rationale**:
- Keeps names concise and consistent
- Follows Django, Flask, and FastAPI conventions
- Makes imports cleaner: `from middleware.logging import LoggingMiddleware`
- Makes imports cleaner: `from middleware.store_context import StoreContextMiddleware`
- Reduces redundancy (the `middleware/` directory already indicates the purpose)
