feat: SQLite database for all credentials, keys, wake schedule, and usage cache

- Add SQLite database at ~/.local/share/dispatch/dispatch.db with tables: credentials, api_keys, wake_schedule, usage_cache
- Store Claude OAuth credentials in DB with import button in Model Status UI
- Store OpenCode/Copilot API keys in DB with paste-to-import modal
- Store OpenCode cookie and workspace IDs in DB
- Migrate wake schedule from .wake-schedule.json to DB
- Migrate usage cache from in-memory Map + localStorage to DB
- Remove all env var and file fallbacks — DB is the single source of truth
- Add seed scripts: bin/import-credentials.ts, bin/seed-opencode-keys.ts
- Docker: container runs as host UID/GID with matching home directory
- Clean up dispatch.toml: remove env fields, update comments
- Progress bar time markers for usage cycle tracking
