v1.5.0: Pluggable activity reporting engine, CLI, and Web UI

- Register new console script `aiosyslogd-activity` pointing to the CLI.
- Implement the `aiosyslogd.activity` module to execute async, chunked
  SQLite queries with FTS5 and bucket active minutes by user, category, and app.
- Define a pluggable `BaseActivityParser` architecture and implement
  `FortiOSParser` to extract app, user, and appcat attributes via regex.
- Implement a terminal-optimized CLI (`aiosyslogd-activity`) featuring
  terminal-width detection and responsive single or dual-column table views.
- Add `/activity` and `/api/activity` endpoints to the Quart web server
  along with corresponding template integration.
- Add comprehensive unit tests covering the new activity engine, parsers,
  and CLI, and update existing test fixtures to reset config caching.

v1.3.2: Separate debug settings per component

- Removed forced debug override from server.py; each driver now reads
  its own debug setting from config instead of inheriting [server].debug.

- Added debug setting to [database.sqlite] and [database.meilisearch]
  sections for independent per-component debug control.

- Moved sql_dump from [database] to [database.sqlite] (SQLite-specific).

- Updated README.md to reflect separate debug settings:
  - [server].debug: syslog parsing errors only
  - [database.sqlite].debug: SQLite operations
  - [database.meilisearch].debug: Meilisearch operations

- Updated default config (config.py, default-aiosyslogd.toml) and
  aiosyslogd.toml to match new structure.

- Updated SQL_DUMP lookup to read from [database.sqlite] section for
  TRACE log level determination.

This allows fine-grained debugging: enable database operation logs
without verbose syslog parsing output, and vice versa.

v1.3.1: Fix database retention cleanup bug

- Fixed incorrect deletion of middle database files during cleanup
- Simplified retention logic: keeps N months total (was: current + N older)
- Moved retention_months to [database.sqlite] config section
- Updated README and default config accordingly

v1.3.0: Database file auto cleanup with retention_months config

v1.1.1: Fix event loop info retrieval in server and web modules

- Replace deprecated asyncio.get_event_loop() calls with safer
  asyncio.get_running_loop() where appropriate
- Add a helper function in server.py that gracefully handles cases
  where no event loop is running yet
- Update logging to show the correct event loop module being used
