Fix critical issues: router method enforcement, cron localhost guard, rate limiter file-based, entity update_at optional, device race condition, area remove transaction, control scripts static flush

Add high-complexity PHPUnit tests: retry/backoff, auth guard, transactions, happy-paths, script state ...

- Refactor Base.php: extract executeCurl/getCurlInfo for mockability
- Refactor App.php: split api_auth_guard into check_api_auth (testable) + guard wrapper
- Refactor Devices.php: add optional ?Base DI to connect_new_device
- Update TestApp.php: add control_scripts_instances for script tests
- Update bootstrap.php: define PHPUNIT_TEST to skip new App() autoload side-effect

New test files:
- DeviceAPIBaseRetryTest (7 tests) — retry/backoff with mock cURL
- AppAuthGuardTest (7 tests) — auth + rate limiter without exit
- DevicesModelTransactionTest (4 tests) — happy path, rollback, mode checks
- AreasControllerHappyPathTest (7 tests) — full area CRUD success flows
- ScriptsModelStateTest (8 tests) — scope list, script state, enable/disable

Total: 113 tests, 285 assertions — all passing.

Phase 2: Data integrity & error handling (ErrorHandler, transactions, silent SQL, HTTP statuses, dead stubs)

Bugfixes. Webclient. DataProvider ...

Server:
- Models/Devices: alias_is_uniq excludes removed devices
- ErrorHandler: skip error page output if headers already sent

Webclient:
- DataProvider: getOrFetch, invalidate, invalidatePrefix, getCollection
- Areas cache: AreasApi.list caches raw.areas.list; placeInArea uses getOrFetch
- Cache invalidation after area/device mutations
- areaDetailsModal reads from DataProvider instead of DOMObject.provideData
- areas-tree: fix self-referencing and cycle-breaking in makeTree/renderingBranch
- placeInArea: fix unassign button not appearing after first place action
- index.php: safe TEXTMSGS parsing via PHP json_decode, no JS template literal injection
- webclient/config.php: version bump, server URL updated
- DOCS.md: DataProvider full API reference
