Combined dependency updates (#1105)

Combines several open bot PRs into one:

- Bump Gradle Wrapper from 9.7.1 to 9.8.2 (squashed): closes #1098,
closes #1099, closes #1100, closes #1101, closes #1102
- Bump the github-actions group (`init-integ-test` action): closes #1096
- Bump references to Develocity Gradle plugin from 4.6.0 to 4.6.1:
closes #1103
- Bump the npm-dependencies group with 10 updates: closes #1097

Notes:
- `nock` moves from 14 to 15, a major version bump. Tests that intercept
HTTP requests are the most likely to break.
- Local `npm run build` (prettier + eslint + esbuild) passes under node
24.22.1. Locally, jest passed 490/491. The one failure is `fetches
wrapper jar checksums for snapshots`, which hits the live
services.gradle.org API and timed out at 60s on a slow connection. I
didn't check whether it also fails on `main`, so CI will settle it.

Also included:
- Switch the solutions Develocity server URL from
`ge.solutions-team.gradle.com` to `solutions.develocity.cloud`. The old
host now 308-redirects to the new one. `@actions/http-client` strips the
`Authorization` header on a cross-host redirect, so the short-lived
token request failed with a 401, which broke all the Develocity
injection integ tests.
