v0.4.4: multi-line Apps Script ID input (one per line)

Follow-up to v0.4.3 — users asked for one-ID-per-line instead of
comma-separated, which is easier to edit in the UI. Field is now a
3-row textarea with a rolling hint underneath:

- 0 or 1 IDs: 'Tip: add more IDs for round-robin with auto-failover'
- 2+ IDs:    'N IDs — round-robin with auto-failover on quota'

The parser accepts both newlines and commas as separators, so existing
configs keep loading cleanly. Closes #1.
