fix: auto-load .teaagent/env into os.environ at startup

The .teaagent/env file written by 'teaagent setup --write-env' was never
automatically sourced into the Python process, causing LLM adapters to fail
with 'requires OPENCODEZEN_API_KEY' when the user had not manually run
'source .teaagent/env' in their shell.

- Add _load_env_file() to ergonomics/workspace_defaults.py that parses
  .teaagent/env and loads export KEY=VALUE into os.environ (without
  overwriting existing env vars)
- Call it from load_workspace_defaults() so both TUI and CLI paths
  pick up the env file automatically
- Fix mypy error in audit.py:151 (Fernet type narrowing on Optional[bytes])
- Add 13 unit tests covering all edge cases (missing file, quotes,
  overwrite protection, integration path, etc.)

Constraint: .teaagent/env must not overwrite already-set os.environ values
Tested: mypy clean (330 files), ruff clean, 3515 tests passed
Confidence: high
