Add unified config system (issue #24)

Introduce timetracker/config.py with a single config() helper that resolves
settings from a fixed priority chain: NAME__FILE (opt-in secret) -> env var
-> .env -> settings.ini -> in-code default. Supports type casting
(bool/list/int/Path), file-based secrets with .strip(), and required_in_prod
validation.

Migrate settings.py off the previous ad-hoc idioms:
- DEBUG via config() (PROD kept as deprecated alias)
- SECRET_KEY required in prod, supports SECRET_KEY__FILE
- APP_URL derives ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS (kept separate,
  each independently overridable); ALLOWED_HOSTS is now configurable
- TZ and DATA_DIR via config()

Fix DATA_DIR inconsistency: entrypoint.sh now reads DATA_DIR (was hardcoded)
so the bash bootstrap and Django agree on the database directory.

Document the container/entrypoint-only flags (PUID/PGID/
CREATE_DEFAULT_SUPERUSER/STAGING/LOAD_SAMPLE_DATA) as bash concerns.

Update deployment configs to set APP_URL (and DEBUG), add docs/configuration.md,
settings.ini.example, regrouped .env.example, CLAUDE.md, and tests.
