Subject: [PATCH] feat: add AdjustAIButton, EditPlanButton, and
 AsignaturaPreviewCard components

- Implemented AdjustAIButton for AI-driven plan adjustments with a confetti effect on success.
- Created EditPlanButton to allow editing of plan details with form validation and optimistic updates.
- Added AsignaturaPreviewCard to display course previews with relevant statistics and details.
- Introduced Field component for consistent form field labeling.
- Developed GradientMesh for dynamic background effects based on color input.
- Added Pulse component for skeleton loading states.
- Created SmallStat and StatCard components for displaying statistical information in a card format.
- Implemented utility functions in planHelpers for color manipulation and formatting.
- Established planQueries for fetching plan and course data from the database.
- Updated the plan detail route to utilize new components and queries for improved user experience.
