Redesign the caching Job Summary (#985)

Redesigns the caching section of the Job Summary into a single,
consistent layout across every cache provider and state, and integrates
the provider message into the report rather than appending it
disconnected at the bottom.

## Motivation

The caching report was produced by three divergent code paths (NoOp /
basic / enhanced), each rendering its own markdown:

- **Explicitly disabled** → a one-line message, no expand, no provider
note.
- **Enhanced** (incl. skipped-due-to-existing-home) → a full `<details>`
block.
- **Basic** → a one-line message with **no** expandable details at all.

The Enhanced/Basic provider note floated at the very bottom,
disconnected from the report.

## What changed

`save()` now returns structured `CacheReport` data instead of
pre-rendered HTML, and a single renderer (`caching-report.ts`) produces
one unified layout for all variants:

- **Section heading**: `#### <icon> Gradle Caching — <Provider>
(<status>)`
- **Status line** explaining what the cache did
- **Integrated provider note** woven in under the heading — now shown
**unconditionally** (no longer gated on license acceptance)
- **Expandable cache-entry details** when there are entries — basic
caching now gets this too

The two disabled variants (explicitly disabled, and skipped due to a
pre-existing Gradle User Home) render as **compact callouts with no
expandable section**.

### Main repo
- `caching-report.ts` (new): central renderer + all framing copy + entry
table/`<pre>` helpers.
- `cache-service.ts`: `CacheReport` / `CacheEntryReport` / status types;
`save()` returns `CacheReport`.
- `cache-service-loader.ts`: `NoOp` returns a report;
`LicenseWarningCacheService` removed; new `getProviderNote()`.
- `cache-service-basic.ts`: builds a `CacheReport`.
- `job-summary.ts` / `setup-gradle.ts`: thread `CacheReport` +
`ProviderNote`.
- `configuration.ts`: remove now-unused `isCacheLicenseAccepted()`.

### Vendored library
The structured contract requires **gradle-actions-caching v0.7.0**
(gradle/actions-caching#74). This PR updates the vendored library to
that release — the official `Update gradle-actions-caching library to
v0.7.0` vendor commit is included here, so merging this PR ships the
redesign together with the library it depends on.

## Testing

- Both repos build; prettier + eslint clean.
- `gradle/actions`: 363/363 Jest tests pass, including new
`caching-report.test.ts` covering every variant.
- `gradle-actions-caching`: 74/74 pass under JDK 17.
- Rendered markdown verified for all five variants (enhanced/basic
enabled & read-only, disabled, skipped).
