Ludy ec3de16c08 ci: centralize Gradle caching across GitHub Actions workflows (#7546)
## Summary

This pull request restructures Gradle dependency caching across the
GitHub Actions workflows.

The central `gradle-cache-prime` job is responsible for preparing the
shared backend Gradle cache. Reusable workflows restore that shared
cache without writing to the same key, while independently triggered
workflows use isolated cache namespaces.

## What changed

### Shared Gradle cache

- Added a stable `gradle-v1-` cache namespace for the shared backend
cache.
- The cache key includes the runner OS, runner architecture, JDK
version, and the relevant Gradle configuration files.
- The cache key is calculated before Gradle runs and reused for the
later save step.
- The prime job performs a lookup first and resolves backend
dependencies only when the exact cache is missing.
- This prevents Gradle or Spotless changes during the prime step from
producing a different save key from the key used by downstream jobs.

### Reusable workflows

- Backend, OpenAPI, license, Docker, E2E, and migration workflows
restore the shared cache instead of writing to the shared key.
- The backend build matrix includes `matrix.jdk-version` in its cache
key.
- Enterprise, Tauri, and generated-model workflows support the
`use_shared_cache` boolean input.
- When `use_shared_cache` is enabled, those workflows restore the shared
cache.
- When it is disabled, they use workflow-specific cache namespaces.

### Independent workflows

Independent workflows now use separate cache prefixes, including:

- `gradle-license-report-v1-`
- `gradle-swagger-v1-`
- `gradle-push-docker-v1-`
- `gradle-tauri-releases-v1-`
- `gradle-deploy-pr-v1-`
- `gradle-playwright-e2e-v1-`
- `gradle-generated-models-v1-`

This prevents them from creating or affecting the shared backend cache
before the prime job.

### Build and E2E flow

- Removed the `-PnoSpotless` option from the central Gradle
dependency-resolution command.
- Removed the separate Gradle dependency prime/retry logic from the live
E2E workflow.
- Connected the Tauri build and generated-models check to the central
cache-prime job.

## Motivation

Previously, multiple workflows could use and save the same Gradle cache
key independently. The first workflow to save the cache could therefore
determine its contents, even if it had resolved a different or
incomplete set of dependencies.

The cache key was also evaluated after some Gradle tasks had run. If
Gradle or Spotless modified a file covered by `hashFiles(...)`, the save
key could differ from the restore key used by downstream jobs.

This change gives the shared cache a single owner, isolates
workflow-specific caches, and makes cache usage deterministic across the
CI pipeline.

## Expected result

- `gradle-cache-prime` is the single writer for the shared backend
Gradle cache.
- Downstream jobs restore the same cache without competing cache writes.
- Independently triggered workflows remain isolated through their own
cache namespaces.
- Changes to the monitored Gradle configuration files produce a new
cache key.
- The normal Gradle/Spotless path is included when the shared cache is
populated.

## Validation

- Compared the cache key expressions and `hashFiles(...)` inputs across
the affected workflows.
- Verified that the central restore and save steps use the same
precomputed key.
- CI should confirm that the prime job populates the shared cache and
downstream workflows only restore it.
