Subject: [PATCH] chore: add Dependabot config for npm, cargo, and actions

Closes #54.

Schedules weekly updates for:
- root npm (split into production / development groups)
- docs/ npm (grouped)
- backend/ cargo
- render/ cargo
- github-actions

Caps are set per-ecosystem to keep the inbound PR volume sane.
