add lookback period and note strictness dropdowns to onboarding

Add two preference dropdowns to the Connected Accounts step:
- Lookback period (1 week / 1 month / 3 months) for Gmail and Fireflies sync
- Note strictness (Auto / High / Medium / Low) with inline descriptions

Replaces hardcoded LOOKBACK_DAYS in sync_gmail and sync_fireflies with
configurable value from ~/.rowboat/config/lookback.json. Adds IPC channels
for reading/writing both configs. SelectItem now supports a description
prop rendered only in the dropdown, not the trigger.
