feat: enhance theme customization and UI components

- Implemented a new color generation module to create CSS variables based on a single hue value, supporting both light and dark modes.
- Added unit tests for the color generation logic to ensure accuracy and robustness.
- Replaced dropdown location filter with tab navigation in RulesManagerPage and SkillsManagerPage for improved UX.
- Updated app store to manage custom theme hues and states, allowing for dynamic theme adjustments.
- Sanitized notification content before persisting to localStorage to prevent sensitive data exposure.
- Refactored memory retrieval logic to handle archived status more flexibly.
- Improved Tailwind CSS configuration with new gradient utilities and animations.
- Minor adjustments to SettingsPage layout for better visual consistency.
