fix(security): resolve path-injection, B701, B101, B112 Bandit alerts

- Path injection (B614): centralized safe_resolve_path in core/utils.py,
  refactored 6 UI modules to use it with safe_root validation
- B701: added explicit autoescape=select_autoescape() to Jinja2
  Environment() calls in 3 files
- B101: replaced assert statements with proper if/raise patterns in
  12+ files (partial)
- B112: added logger.warning() to bare except:continue blocks in
  5 files
