[FEAT]: Attached the Updates page in the settings

[Circuit-Overtime]

Changes Made

• apps/settings/main.py — Replaced three inline OTA rows (Version / Check Update / Install Update) with a single "Version" action row that opens the dedicated Updates app. Removed ~100 lines of OTA logic (_check_update, _install_update, _set_ota_status, _ota_safe) from Settings.
• apps/about/main.py — Added BTN_A handler so pressing A on the About page launches the Updates app, matching the Settings → Version flow.
• apps/launcher/main.py — Added "updates" to DRAWER_HIDDEN so the Updates tile doesn't clutter the drawer (reachable from Settings/About only).
• apps/store/main.py — New App Market tile: lists apps_market/ catalogue, install/uninstall via oreoOS.store, scrollable card UI with action chips.
• apps/store/__init__.py — New package init for the Market app.
• CONTRIBUTING.md — Documented the apps/ (default-installed) vs apps_market/ (opt-in) directory distinction and how deploy + Market interact.
• README.md — Updated app count to "14 default apps + an App Market", added App Market section with install/uninstall flow and programmatic API docs, reorganized tile grid.

Checklist

• MicroPython compat: no f-strings with =, no pathlib, no walrus in modules that ship to flash
• App ships through tools/deploy.py DEPLOY list / tools/build_release.py SHIP_PATTERNS
• No secrets committed (.env, secrets.py)
• Flashed + smoke-tested on hardware
• Tested locally:
