Subject: [PATCH] feat: Security and i18n improvements for Smart Mind Map
 plugin

- Fixed high-severity XSS and JS injection vulnerabilities by safely escaping IDs and user input using `json.dumps` and HTML entity encoding.
- Prevented potential DoS crashes caused by curly braces in LLM output by replacing `.format()` with safe string replacement.
- Refactored language resolution into a `_resolve_language` helper method, implementing base language fallback (e.g., `fr-BE` -> `fr-FR`).
- Refactored date formatting to use a cleaner, dictionary-based approach.
- Consolidated i18n logic into a single file with robust fallback handling.
- Verified all changes with comprehensive unit and security tests.
