UI improvements: filter buttons, note detail styling

- Color-code filter buttons to match note types: grey (all), green (my shared), blue (shared with me), pink (job), orange (manager), amber (personal)
- Decrease note detail container width: max-w-4xl → max-w-2xl
- Increase body text area height to 224px with min-height on display
- Hide Audio/Attachments labels when no content present
- Remove placeholder text for empty audio/attachments sections
