fix: harden token search with pagination, rate limiting and input validation

- Add configurable per-user token creation limit (max_user_tokens)
- Sanitize search input patterns to prevent expensive queries
- Add per-user search rate limiting (by user ID)
- Add pagination to search endpoint with strict page size cap
- Skip empty search fields instead of matching nothing
- Hide internal errors from API responses
- Fix Interface2String float64 formatting causing config parse failures
- Add float-string fallback in config system for int/uint fields
