Add Remnic

[earlvanze]

Summary

Adds Remnic 9.49.0 as a standalone Umbrel app for local-first agent memory over HTTP and MCP.

• Uses Remnic’s official public multi-architecture container image.
• Persists memory, configuration, and QMD index state under the app data directory.
• Protects the admin dashboard with Umbrel authentication and requires the per-install bearer token for MCP and HTTP API clients.
• Displays the deterministic Umbrel app password for use as the Remnic bearer token.
