### Context & Goal

Enhance the user experience by standardizing the look and feel of Discord embeds. Adding consistent branding like a custom footer (with version info) and using the bot's accent color will make the bot feel more professional.

### Dependencies

- None

### Affected Files

- `bot/lib/embeds.ts`: Update standard embed creators.
- `shared/lib/constants.ts`: Add branding-related constants (colors, footer text).

### Technical Constraints & Strategy

- Implementation: Update `createBaseEmbed` and other helpers to automatically include footers and standard colors.
- Use info from `package.json` for versioning in the footer.
- Ensure the changes don't break existing layouts where custom colors might be needed.

### Definition of Done (Binary)

- [x] All standard embeds now include a consistent footer.
- [x] Embeds use a predefined brand color by default.
- [x] Version number is automatically pulled for the footer.

### New Test Files

- None.
