Move X-BanGUI-Request header name/value to backend/app/utils/constants.py as single source of truth. Add GET /api/v1/config/security-headers endpoint. Update csrf middleware, frontend api client, and docs to use shared constants.
Add explicit HTTP status code documentation to every endpoint
across 15 router files. Each endpoint now declares all possible
response codes (200/201/204/400/401/404/409/429/502/503) with
descriptions so frontend can distinguish error types.

Models in app/models/ are now pure data classes with no cross-layer dependencies.
This ensures the models layer remains a true leaf node in the dependency graph.
Changes:
- Create app/models/_common.py with shared types (TimeRange, bucket_count, constants)
- Move TimeRange and time-range constants from ban.py to _common.py
- Update history.py, routers, and services to import from _common.py
- Remove imports from app.config and app.utils from config.py models
- Move field validators from models to router layer:
- Add log_target validation in config_misc router
- Add log_path validation in jail_config router
- Update test_models.py to reflect validators moved to router layer
- Update documentation (Architekture.md, Backend-Development.md) with model layering rules
- Fix import ordering and type annotations in affected files
Model layering rule: Models may only import from:
✓ Standard library and third-party packages (Pydantic, typing)
✓ Other models in app/models/ (sibling models)
✓ app.models.response (response envelopes)
✗ app.services, app.config, app.utils, or any application layer
Validation requiring app-level state (settings, allowed directories) now happens
at the router or service layer, not in model validators.
Fixes: Models were not true leaf nodes due to circular imports and app-layer dependencies

This commit enforces the repository boundary by eliminating direct database connection
dependencies (DbDep) from all routers. Routers now depend on service context dependencies
that combine the database connection with the related repositories.
Changes:
- Add 5 service context dependencies in dependencies.py:
* SessionServiceContext: db + session_repo
* BlocklistServiceContext: db + blocklist_repo + import_log_repo + settings_repo
* SettingsServiceContext: db + settings_repo
* BanServiceContext: db + fail2ban_db_repo
* HistoryServiceContext: db + fail2ban_db_repo + history_archive_repo
- Refactor all 9 routers (auth, bans, blocklist, config_misc, dashboard, geo,
history, jails, setup) to use service contexts instead of DbDep.
- Update Backend-Development.md with clear examples of the new pattern and
documentation of available service contexts.
Rationale:
- Enforces the repository boundary through the dependency system
- Makes database operations explicit and auditable
- Improves testability by allowing service contexts to be mocked
- Prevents accidental direct database access from routers
The deprecated DbDep remains available for backward compatibility with
services that have not yet been refactored, but routers can no longer import it.

- Add @field_validator for fail2ban_start_command to validate with shlex.split()
at startup, catching misconfigured commands with mismatched quotes
- Replace .split() with shlex.split() in jail_config.py line 450
- Replace .split() with shlex.split() in config_misc.py line 154
- Update Backend-Development.md with configuration documentation explaining
quoted path handling and common pitfalls
- Add comprehensive test suite (8 tests) covering valid commands, quoted paths,
and mismatched quote errors
This fix ensures commands like '/opt/my tools/fail2ban-client' start are
correctly parsed as two tokens instead of three, preventing execution failures
when the path contains spaces.
