Introduces the SQLite-backed region registry and channel->region mapping
that will drive the per-channel flood-scope feature. No UI or device
wiring yet; those land in subsequent PRs.
- schema.sql: new `regions` and `channel_scopes` tables + partial index
on the default flag.
- database.py: CRUD helpers for regions (create/list/get/delete/default)
and channel_scopes (set/get/bulk-load) with ON DELETE CASCADE.
- app/meshcore/regions.py: pure helpers for SHA256('#'+name)[:16] key
derivation and firmware-compatible name validation (mirrors the
`RegionMap::is_name_char` rule `c in {-,$,#} or c>='0' or c>='A'`).
- tests/test_regions.py: known SHA256 vectors, validator coverage
(incl. the firmware quirk that `_` and other 0x5B-0x60 chars are
admitted), and CRUD + cascade integration tests.
Backup filenames now derive from the active DB stem (e.g. mc_9cebbd27.2026-03-24.db).
Listing and cleanup glob *.db so existing mc-webui.* backups remain visible.

All settings (protected_contacts, cleanup_settings, retention_settings,
manual_add_contacts) moved from .webui_settings.json file to SQLite database.
Startup migration auto-imports existing file and renames it to .json.bak.
Added safeguard in _on_new_contact: if firmware fires NEW_CONTACT for a
contact already on the device, skip pending and log a warning. Also added
diagnostic logging showing previous DB state (source, protected) when
contacts reappear as pending.

Reads the existing .msgs JSONL file and imports channel messages and DMs
into the v2 SQLite database. Runs automatically when device connects and
DB is empty. Handles sender parsing, pubkey resolution, and FK constraints.

- Add pkt_payload column to direct_messages table for stable packet
hash generation and Analyzer URL linking
- Update insert_direct_message() and DeviceManager to store pkt_payload
- Add test for DM pkt_payload storage (43 tests pass)
- Update watchdog to monitor only mc-webui (meshcore-bridge removed)
- USB reset trigger now fires for mc-webui container failures
