sync_floors.py only updates copybot.paper.json (paper bot). The live
bot's config.live.json floors were never auto-updated (HANDOFF.md:
'nothing auto-writes it'), so manually-added wallets kept their
floor forever.
New sync_live_floors.py mirrors paper floors into config.live.json:
- Reads floors (and floor_pin overrides) from copybot.paper.json
- Updates matching wallets in config.live.json
- Only writes if something changed
Added to daily.sh right after sync_floors.py, so both configs stay
in sync every day.
