BUG] Fix the apps sync over github and prepare entry for CLI

[Circuit-Overtime]

Changes Made

• apps/bt/main.py — Auto-starts a scan when BT is toggled on so nearby devices appear immediately; replaces stub "Pair queued" notification with real start_pair() call and surfaces success/failure in the notification; contextual hint bar now shows "A=Connect" on a nearby device row vs "A=toggle" elsewhere.
• apps/store/main.py — Switched item["installed"] to item.get("installed") to avoid KeyError on catalogue entries that haven't had the flag back-filled yet.
• oreoOS/store.py — Removed stale module-level docstring; after each refresh(), stamps installed on every catalogue entry and prunes orphaned .py icon files from the icons cache dir.
• oreoOS/config.py — Bumped VERSION from v1.4.26 → v1.4.28.
• tools/deploy.py — Added --override=<csv> (and bare --override defaulting to gallery,reader) flag that wipes named app trees on device before the push and drops their hash-cache entries so they get re-uploaded in the same run.

Checklist

• MicroPython compat: no f-strings with =, no pathlib, no walrus in modules that ship to flash
• No secrets committed (.env, secrets.py)
• Flashed + smoke-tested on hardware
• Tested locally:
