Fix input_text max length constraint for mode colors

- Add max: 255 parameter to adaptive_lighting_mode_colors input_text
- Minify JSON to fit within Home Assistant's 100 character default limit
- Remove adaptive_lighting_mode_settings input_text (too long, convert to comments)
- Remove get_mode_settings script (no longer needed)
- Fix template syntax: use states() instead of state_attr() for input_text values
- Convert mode settings to reference documentation comments

This fixes the 'Initial value length not in range 0-100' error from Home Assistant.
