Implement dynamic column reordering with numeric order field and realtime sync

- Add order field to all columns in DEFAULT_SETTINGS (1-47)
- Settings page: reorder columns via numeric input or up/down arrows, autosave after 400ms
- Estimator table: render columns in order specified by order field, refresh on settings updates
- Normalize column orders on load and realtime updates with fallback for missing order
- Add logging to trace column order changes through settings and estimator pages
- Reset button reinitializes all settings to defaults with proper column ordering
- Table reload prevents concurrent requests to avoid PocketBase auto-cancellation
