Merge origin/main into branch, resolving conflict in app/database.py.
Combined improvements from both branches:
- Keep pool_pre_ping=True and structured variable approach from feature branch
- Add explicit QueuePool import and poolclass assignment from main
The QR code on /qr-login was not rendering because it depended on loading
qrcode@1.5.4 from the jsdelivr CDN, which may be blocked in some network
environments.
- Add segno>=1.6.0 (pure-Python QR library, no Pillow needed) to requirements.txt
- Generate QR code as a base64 SVG data URI server-side in the challenge endpoint
- Add qr_code_svg field to CreateChallengeResponse Pydantic model
- Replace canvas+CDN script in qr_login.html with an <img :src="qrCodeSvg">
- Remove the $nextTick/QRCode.toCanvas() client-side rendering block
- Extract QR rendering parameters (_QR_ERROR_LEVEL, _QR_SCALE) as module constants

- Add db_pool_size, db_max_overflow, db_pool_timeout, db_pool_recycle fields to app/config.py
- Add upload_rate_limit_per_user, upload_rate_limit_window fields to app/config.py
- Update app/database.py to use NullPool for SQLite and QueuePool with config-driven
pool settings for PostgreSQL/MySQL
- Add all 6 settings to SETTING_METADATA in app/utils/settings_service.py
Fixes test_all_config_settings_have_metadata failure

Add missing SETTING_METADATA entries for db_pool_size, db_max_overflow,
db_pool_timeout, db_pool_recycle, upload_rate_limit_per_user, and
upload_rate_limit_window so the test_all_config_settings_have_metadata
test passes.

Override require_upload_rate_limit with a no-op in the test client
fixture so that upload-heavy test suites (test_file_upload.py) are not
rejected with 429 Too Many Requests when Redis is available in CI.

Introduces a Redis-backed sliding-window rate limiter for upload
endpoints (/api/ui-upload, /api/process-url) that:
- Enforces per-user limits (default: 20 uploads / 60 s)
- Dynamically reduces limits under system stress (queue depth, CPU load)
- Returns 429 with Retry-After header when exceeded
- Fails open when Redis is unavailable
- Works with the existing client-side adaptive back-off

SQLite engines now use NullPool instead of QueuePool, eliminating the
"QueuePool limit of size 5 overflow 10 reached" TimeoutError under
concurrent load. PostgreSQL/MySQL engines use a configurable QueuePool
with sensible defaults (pool_size=10, max_overflow=20) exposed via
DB_POOL_SIZE, DB_MAX_OVERFLOW, DB_POOL_TIMEOUT, DB_POOL_RECYCLE env
vars. pool_pre_ping is enabled on all backends.

The QR login page countdown timer compared the server's UTC expiration
timestamp against the client's local clock, causing the QR code to appear
immediately expired when the client clock was ahead of the server.
Changes:
- Add ttl_seconds field to CreateChallengeResponse (seconds until expiry)
- Frontend countdown now uses relative elapsed time since response was
received, eliminating clock-skew issues
- Mobile app: replace alert-only QR button with actual camera-based
QR code scanner using expo-camera
- Add QRScannerScreen with barcode scanning, permission handling, and
scan area overlay
- Update camera permission description to mention QR code scanning
- Add tests for ttl_seconds computation
