feat: update langbot-plugin to version 0.3.7

Add ability for admin operators to take over user conversation sessions
from the AI bot, manually reply as the bot, and release sessions back to
AI processing.

Backend:
- New HumanTakeoverSession DB model and migration (v26)
- HumanTakeoverService with in-memory cache for hot-path performance
- REST API endpoints for takeover/release/send-message/list/detail
- Message interception in botmgr.py (after webhook, before pipeline)

Frontend:
- Takeover/release controls in BotSessionMonitor chat header
- Operator message input bar with visual distinction (orange theme)
- Taken-over session indicators in session list
- 3-second auto-refresh polling during active takeover
- Full i18n coverage across all 7 locales

-- LangBot uses [Alembic](https://alembic.sqlalchemy.org/) to manage database migrations, supporting both SQLite and PostgreSQL. Migration files are located in `src/langbot/pkg/persistence/alembic/versions/`. If you changed the definition of database entities (ORM models), generate a new migration script by running `uv run python -m langbot.pkg.persistence.alembic_runner autogenerate "description of your change"` in the project root (requires `data/config.yaml` to exist). Review and edit the generated script before committing. Migrations are executed automatically on LangBot startup. For data migrations (e.g. modifying JSON field content), you need to manually add the migration code in the generated script.
+- If you changed the definition of database entities, please update the migration file in `src/langbot/pkg/persistence/migrations/` and update the constants.py file in `src/langbot/pkg/utils/constants.py` with the new migration number.
