ZEPAI-676: Remove fuzzy query in fulltext search to avoid errors with large queries

[prasmussen15]

[!IMPORTANT] Remove fuzzy query from fulltext_query() in search_utils.py to prevent errors with large queries.

• Behavior:
  • Removed fuzzy query component from fulltext_query() in search_utils.py.
  • Simplifies query by using lucene_sanitize(query) instead of lucene_sanitize(query) + '~'.
• Functions:
  • fulltext_query() no longer appends ~ to the sanitized query string.
• Misc:
  • Update version in pyproject.toml from 0.3.11 to 0.3.12.
