test(posts): add comprehensive integration test suite

Add 4 test files covering full post creation flow:

1. post_creation_test.go - Service layer tests (11 subtests)
- Happy path with DID and handle resolution
- Validation: missing fields, invalid formats, length limits
- Content label validation (nsfw, spoiler, violence)
- Repository tests: create, duplicate URI handling

2. post_e2e_test.go - TRUE end-to-end test
- Part 1: Write-forward to live PDS
- Part 2: Real Jetstream WebSocket consumption
- Verifies complete cycle: HTTP → PDS → Jetstream → AppView DB
- Tests ~1 second indexing latency
- Requires live PDS and Jetstream services

3. post_handler_test.go - Handler security tests (10+ subtests)
- Reject client-provided authorDid (impersonation prevention)
- Require authentication (401 on missing token)
- Request body size limit (1MB DoS prevention)
- Malformed JSON handling
- All 4 at-identifier formats (DIDs, canonical, @-prefixed, scoped)
- Unicode/emoji support
- SQL injection prevention

4. helpers.go - Test utilities
- JWT token generation for test users

All tests passing. Coverage includes security, validation,
business logic, and real-time indexing.
