3a76453828 security: implement CRYPTO-001 and TIMING-001 remediations 
CRYPTO-001: Certificate serial collision detection
- Add _generate_unique_serial() helper for database-backed PKI
- Add _generate_unique_serial() method for in-memory PKI class
- Check database for existing serial before certificate issuance
- Retry with new random serial if collision detected (max 5 attempts)

TIMING-001: Constant-time database lookups for sensitive queries
- Add dummy PBKDF2 verification when paste not found
- Prevents timing-based enumeration (attackers can't distinguish
  'not found' from 'wrong password' by measuring response time)

098789ff89 allow untrusted certs to manage own pastes 
Split authentication into two functions:
- get_client_fingerprint(): Identity for ownership (any cert)
- get_client_id(): Elevated privileges (trusted certs only)

Behavior:
- Anonymous: Create only, strict limits
- Untrusted cert: Create + delete/update/list own pastes, strict limits
- Trusted cert: All operations, relaxed limits (50MB, 5x rate)

Updated tests to reflect new behavior where revoked certs
can still manage their own pastes.

1f09f2686a fpaste: consolidate code and add type hints 
- Add type hints throughout (NoReturn, Path | None, etc.)
- Extract helper functions to eliminate duplication:
  - read_config_file() / write_config_file()
  - parse_error() for JSON error parsing
  - format_paste_row() / print_paste_list()
  - prepare_content(), extract_paste_id()
  - auth_headers(), require_auth()
- Add constants (CONFIG_DIR, CONFIG_KEYS, MIME_EXTENSIONS)
- Replace if/elif chains with command dispatch tables
- Extract build_parser() from main()
- Use walrus operators and frozenset where appropriate
