Add photo management for models and employees; fix stale detail navigation
Model photos: upload/replace/delete on /api/models/<id>/image (admin),
stored under instance/modelimages/ with a public serve route; thumbnail
plus Upload/Replace/Remove controls in the Models settings modal; the
URL field remains as a manual alternative.

Employee photos, mode-aware: self-hosted directory employees get
upload/replace/delete (photo-<sso> under instance/employeephotos/,
employees plugin migration 0002); external directory mode passes the
HR-supplied picture URL through read-only (writes 409). One resolver
feeds both consumers - the shopfloor recognition/recert kiosk cards and
the employee detail hero - in either mode.

Navigation fix: router-view is keyed on route path, so following a
relationship link between two assets of the same type (machine ->
dualpath machine) reloads the page instead of showing stale content;
query-only URL changes still avoid a remount.

# Backup and Restore
Each site owns its own data (single-tenant, ADR-004), so backups are the site's
responsibility. A complete backup is two parts:
1. **The MySQL database** - all asset, user, audit, and settings data.
2. **The `instance/` directory** - uploaded floor plans, branding assets,
`plugins.json` (the enabled-plugin list), and any tokens or files the app
writes to disk. These are NOT in the database, so a DB-only backup loses
them. Back up `instance/` alongside every database dump.
Restoring the database without the matching `instance/` directory leaves the
app pointing at floor plans and logos that no longer exist.
## What to back up
| Item | Location | Why |
|------|----------|-----|
| Database | MySQL `shopdb_flask` | All application data. |
| `instance/branding/` | repo `instance/` dir | Uploaded logos and favicon. |
| `instance/modelimages/` | repo `instance/` dir | Uploaded vendor-model photos. |
| `instance/employeephotos/` | repo `instance/` dir | Uploaded self-hosted employee photos (external mode serves photos from the HR database instead). |
| `instance/` floor plans | repo `instance/` dir | Uploaded map blueprints. |
| `instance/plugins.json` | repo `instance/` dir | Which plugins this site enabled. |
| `.env` | repo root (offline, secured) | Secrets needed to bring the stack back up. Store separately from the data backup, in a secrets manager. |
## Backup
### Database (Docker)
```bash
docker compose exec -T db mysqldump \
-u root -p"${MYSQL_ROOT_PASSWORD}" \
--single-transaction --routines --triggers \
shopdb_flask | gzip > shopdb-$(date +%F).sql.gz
```
`--single-transaction` gives a consistent dump without locking the tables (InnoDB).
### Database (external MySQL, no container)
```bash
mysqldump -h <host> -u <user> -p \
--single-transaction --routines --triggers \
shopdb_flask | gzip > shopdb-$(date +%F).sql.gz
```
### instance directory
```bash
tar czf instance-$(date +%F).tar.gz instance/
```
Recommended cadence: nightly database dump to offsite storage, 14-day
retention; `instance/` captured on the same schedule (and always right before an
upgrade). Verify a restore quarterly.
## Restore
Restoring replaces the current database contents. Do it into a known-empty or a
throwaway target first if you are unsure.
### Step 1: Bring up the stack (or a fresh one)
```bash
cp .env.example .env # or restore your saved .env
# ensure MYSQL_* and DATABASE_URL match the dump's database name (shopdb_flask)
docker compose up -d db
```
Wait for the `db` container to report healthy (`docker compose ps`).
### Step 2: Load the database dump
```bash
gunzip -c shopdb-2026-07-10.sql.gz | \
docker compose exec -T db mysql -u root -p"${MYSQL_ROOT_PASSWORD}" shopdb_flask
```
For an external MySQL:
```bash
gunzip -c shopdb-2026-07-10.sql.gz | mysql -h <host> -u <user> -p shopdb_flask
```
If the target database does not exist yet, create it as utf8mb4 first (matching
the schema charset):
```sql
CREATE DATABASE shopdb_flask CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
```
### Step 3: Restore the instance directory
```bash
tar xzf instance-2026-07-10.tar.gz # restores ./instance/
```
The docker-compose api container reads `instance/` from the repo working
directory; make sure it is present before starting `api`.
### Step 4: Bring up the API and reconcile migrations
```bash
docker compose up -d api
docker compose exec api flask db upgrade
```
`flask db upgrade` is a safety net: if the dump predates the current code, this
applies any newer migrations. If the dump is at the same version it is a no-op.
### Step 5: Verify
- Log in with a known account.
- Confirm the floor map renders (branding and map blueprints resolve from
`instance/`).
- Spot-check a few asset records and the audit log.
- `curl -s -X POST -H "Content-Type: application/json" -d '{}' http://localhost:5001/api/auth/login | jq .`
should return a `VALIDATION_ERROR`, not a 500.
