Fix: Restore file truncation backward compatibility and fix regressions (#2022)

* fix: restore file truncation backward compatibility and fix regressions

Fixes #1934

- Setting maxReadFileLine=-1 provides equivalent functionality for reading entire files
- Revert to system-controlled maxReadFileLine for file truncation, fixing regressions with:
  - Overridden system prompts lacking auto_truncate parameter information
  - Insufficient user control over truncation behavior
- Add 'Always read entire file' checkbox for easier access to full file reading
- Update translations across all locales with improved descriptions
- Update truncation notice to be more concise

* test: add comprehensive tests for read_file maxReadFileLine settings

- Tests behavior when maxReadFileLine is -1 (reads entire file)
- Tests behavior when maxReadFileLine >= file length (reads entire file)
- Tests behavior when maxReadFileLine is 0 (shows only definitions)
- Tests behavior when maxReadFileLine < file length (truncates content)
- Verifies exact line counts in responses
- Adds helper functions for response validation
- Includes DEBUG flag for controlled logging
