Add system memory monitoring, Bedrock support, and Discord integrations

- Add CPU/GPU memory monitoring endpoint and frontend widget - Add Amazon Bedrock model support (API key / inference profiles) plus model selector entries - Add Discord weather/laundry notification job (JMA forecast + LLM-generated message) - Add Discord bot that replies to mentions via the configured LLM, with weather-aware context - Add scheduled "useless tips" job with separate webhook and quiet-hours skip - Switch FastAPI startup to lifespan handler, log viewer, markdown rendering, and toast UI additions Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
