refactor(routes): review and fix config/bot/ directory (T16)

- Fixed import order in bot.tsx, ChatSection.tsx and Hook files
- Replaced 'as any' with specific type assertions (ExpressionConfig, PersonalityConfig, etc.)
- All files now comply with AGENTS.md import rules
- Build passes with zero errors
- LSP diagnostics clean on all modified files

Changes:
- bot.tsx: Reorganized imports (React first, then third-party, then @/, then ./)
- ChatSection.tsx: Fixed import order
- *SectionHook.tsx (4 files): Added type imports, replaced 'as any' with typed assertions

Note: ProcessingSection (1121 lines) and ExpressionSection (996 lines)
not split due to tight coupling and clear responsibilities.
