feat(ci): add auth image tag update to deploy-dev (#57)

Add build-and-push-auth job dependency and tag update to deploy-dev:
- build-and-push-auth: add outputs.calver_tag for downstream jobs
- deploy-dev: needs both build-and-push and build-and-push-auth
- deploy-dev: set auth image tag in dev overlay via kustomize

-# CartSnitch Monorepo
-
-CartSnitch is a self-hosted grocery price intelligence platform. This repo consolidates the core services and the flagship frontend PWA.
-
-## Services
-
-| Directory | Service | Purpose |
-|-----------|---------|---------|
-| `/` (root) | **Frontend** | React 18 PWA — mobile-first price intelligence UI |
-| `api/` | **API Gateway** | FastAPI — frontend-facing REST API |
-| `common/` | **Common** | Shared Python models, schemas, Alembic migrations |
-| `receiptwitness/` | **ReceiptWitness** | Purchase ingestion via retailer scrapers |
-
-## Quick Start
-
-### Frontend (root)
-
-```bash
-npm install
-npm run dev        # http://localhost:5173
-npm run build      # production build
-npm run test       # unit tests (Vitest)
-```
-
-### Python Services
-
-Each Python service uses [uv](https://github.com/astral-sh/uv) and has its own `pyproject.toml`:
-
-```bash
-cd api             # or common / receiptwitness
-uv sync
-uv run pytest
-```
-
-## Development Workflow
-
-- **Never push directly to main.** Always open a PR from a feature branch.
-- Branch naming: `feature/<description>` or `fix/<description>`
-- Conventional commits: `feat:`, `fix:`, `refactor:`, `docs:`, `chore:`
-
-## Architecture
-
-For full details see [CLAUDE.md](./CLAUDE.md) or the per-service `CLAUDE.md` in each subdirectory.
-
-CartSnitch is a polyrepo-style monorepo: each service can be built and deployed independently, but sharing code between `common/` and the other Python services is done via local path dependencies in `pyproject.toml`.

+# CartSnitch Common
+
+Shared models, schemas, and utilities for CartSnitch services.
+
+## Test Users
+
+The following users are seeded by `cartsnitch-seed` and can be used for local development and UAT.
+
+| Email | Password | Display Name | Notes |
+|---|---|---|---|
+| `uat@cartsnitch.com` | `CartSnitch-UAT-2026!` | UAT Tester | Primary UAT account. Use for regression testing in the CartSnitch frontend. Created by the seed runner via Better-Auth's bcrypt path — credentials work against the live auth service. Idempotent; re-running the seed skips this user if it already exists. |
+
+### Running the Seed
+
+```bash
+# Install with seed dependencies
+pip install -e "cartsnitch-common[seed]"
+
+# Run (requires CARTSNITCH_DATABASE_URL_SYNC)
+CARTSNITCH_DATABASE_URL_SYNC=postgresql://user:pass@localhost:5432/cartsnitch \
+  cartsnitch-seed
+```
+
+### Architecture
+
+- **Models** live in `src/cartsnitch_common/models/`
+- **Alembic migrations** run via the `api` service (`api/alembic/`)
+- **Seed runner** runs via `cartsnitch-seed` (installed as a package entry point)
