fix(frontend): resolve submit spinner hang and data loss issues

Browse Source 
- Add try-catch-finally error handling to handleSubmit and deleteEntries
  functions to ensure submitting state is always reset, even when API calls
  fail or timeout. This fixes the infinite loading spinner bug.

- Preserve genres field after AniList updates, matching the existing tags
  preservation pattern. Prevents genres array from being lost after form
  submission, which was causing "{#each} only works with iterable values"
  error when the page re-rendered.

- Add fallback (|| []) to genres each block to prevent rendering errors
  when genres is undefined or null for entries without genre data.

These fixes ensure robust error handling and data consistency during anime
list updates across AniList, MAL, and Simkl services.

Fixes: submit button spinner never stopping after form submission
Fixes: "{#each} only works with iterable values" error on genres display
