feat: Complete IndieAuth server removal (Phases 2-4)

Completed all remaining phases of ADR-030 IndieAuth provider removal.
StarPunk no longer acts as an authorization server - all IndieAuth
operations delegated to external providers.

Phase 2 - Remove Token Issuance:
- Deleted /auth/token endpoint
- Removed token_endpoint() function from routes/auth.py
- Deleted tests/test_routes_token.py

Phase 3 - Remove Token Storage:
- Deleted starpunk/tokens.py module entirely
- Created migration 004 to drop tokens and authorization_codes tables
- Deleted tests/test_tokens.py
- Removed all internal token CRUD operations

Phase 4 - External Token Verification:
- Created starpunk/auth_external.py module
- Implemented verify_external_token() for external IndieAuth providers
- Updated Micropub endpoint to use external verification
- Added TOKEN_ENDPOINT configuration
- Updated all Micropub tests to mock external verification
- HTTP timeout protection (5s) for external requests

Additional Changes:
- Created migration 003 to remove code_verifier from auth_state
- Fixed 5 migration tests that referenced obsolete code_verifier column
- Updated 11 Micropub tests for external verification
- Fixed test fixture and app context issues
- All 501 tests passing

Breaking Changes:
- Micropub clients must use external IndieAuth providers
- TOKEN_ENDPOINT configuration now required
- Existing internal tokens invalid (tables dropped)

Migration Impact:
- Simpler codebase: -500 lines of code
- Fewer database tables: -2 tables (tokens, authorization_codes)
- More secure: External providers handle token security
- More maintainable: Less authentication code to maintain

Standards Compliance:
- W3C IndieAuth specification
- OAuth 2.0 Bearer token authentication
- IndieWeb principle: delegate to external services

- ADR-050: Remove Custom IndieAuth Server
- Migration 003: Remove code_verifier from auth_state
- Migration 004: Drop tokens and authorization_codes tables
