Merge pull request 'fix(ci): remove GHA cache + simplify Push to match auth (CAR-1357, CAR-1362)' (#54) from betty/car-1362-cache-remove-uat into uat

Two related fixes for build-and-push on Gitea:

1. Drop `cache-from: type=gha` and `cache-to: type=gha,mode=max` from both
   Build and Push steps. `type=gha` is the GitHub Actions Cache backend,
   which does not exist on git.farh.net. The cache export failure was
   marking the Build step failed and skipping the Push step.

2. Simplify the Push step to match the proven-green `cartsnitch/auth/ci.yml`
   pattern: drop `file: ./Dockerfile` (default is `Dockerfile`) and
   `build-args: APT_CACHE_BUST=...` (only used to bust apt cache in stage 1
   of multi-stage build). With these extra params removed, the buildx
   "unknown" error after `pushing layers 0.2s done` resolves itself.

Combined diff: 6 lines removed from .gitea/workflows/ci.yml. This is a
config simplification only — no app code, no build context, no test
changes.

Validated on dev: PR #52 (cache removal) + PR #53 (Push simplification)
