feat: LLM-анализ — индикатор прогресса, кнопка рескана, статистика на дашборде

- Добавлен статус {"status": "analyzing"} в finding.report на время LLM-анализа
- Кнопка рескана (Retry) под LLM-отчётом в ручном режиме
- LLM-статистика на дашборде: analysed / pending
- Защита от двойного анализа через per-finding asyncio.Lock
- _llm_spinner.html — фрагмент спиннера для состояния analysing
- Удалён мёртвый код: constants, i18n, CSS, queries
- Фиксы: _env_int, индексы БД, UnicodeDecodeError, time.mktime и др.
- Шаблоны: shared includes (_status_badge, _pagination)
- AGENTS.md: workflow (lint, test, commit, rebuild)
