## Summary by CodeRabbit

- **New Features**
  - Improved edgeless text block styling to support theme-based color, font, and alignment settings.

- **Style**
  - Updated the default text color in edgeless text blocks to black, with support for separate dark and light mode colors.

- **Bug Fixes**
  - Ensured the color picker and block rendering reflect the updated default color.

- **Tests**
  - Adjusted tests and snapshots to expect the new default color and theme-based color structure.
