Improves dashboard data handling and settings

Refactors the dashboard to improve data fetching, error handling, and overall user experience.

- Prevents errors on refresh by validating company ID.
- Improves date handling from CSV by using a `safeParseDate` function to avoid "Invalid Date" errors.
- Adds a timestamp for when metrics were last updated.
- Fixes a bug where the refresh was failing silently.
- Improves settings page by wrapping form elements with form tags.
- Adds autocomplete attributes on settings page.
- Adds database files to `.gitignore`.
