Replace Uptime Kuma with Gatus for declarative uptime monitoring
All checks were successful
Check Flake / check-flake (push) Successful in 2m4s

Gatus is configured entirely via YAML (mapped from Nix attrsets),
making nix-config the single source of truth for all monitoring
config instead of Uptime Kuma's web UI/SQLite database.

`flake.nix` applies patches from `/patches/` to nixpkgs before building (workaround for nix#3920).
### Service Dashboard & Monitoring
When adding or removing a web-facing service, update both:
- **Gatus** (`common/server/gatus.nix`) — add/remove the endpoint monitor
- **Dashy** — add/remove the service entry from the dashboard config
### Key Conventions
- Uses `doas` instead of `sudo` everywhere

## Git Worktree Requirement
When instructed to work in a git worktree (e.g., via `isolation: "worktree"` or told to use a worktree), you **MUST** do so. If you are unable to create or use a git worktree, you **MUST** stop work immediately and report the failure to the user. Do not fall back to working in the main working tree.
When applying work from a git worktree back to the main branch, commit in the worktree first, then use `git cherry-pick` from the main working tree to bring the commit over. Do not use `git checkout` or `git apply` to copy files directly. Do **not** automatically apply worktree work to the main branch — always ask the user for approval first.
