Improve search functionality

[mohamede1945]

• Resolved issues with the search feature.
• Implemented diacritic-insensitive searching.
• Enhanced search to be insensitive to Unicode categories: Mark (M), Punctuation (P), Symbol (S), and Control (C), as well as the Arabic Tatweel character (U+0640).
• Normalized search strings using Unicode Normalization Form KD.
• Unified search and autocomplete behavior by adopting a consistent matching algorithm.

TODO:

• Integrate Full-Text Search (FTS) for enhanced searching capabilities.
• Extend search functionality to include all downloaded translations and tafseers.
• Implement collapsible search results, allowing users to collapse specific results for easier navigation to subsequent entries.
