[FR] setting webUrl separate from cloneUrl

[xPartyBear]

With a self-hosted GitLab it is possible to have a url like https://api.mygitlab.com for services to use tokens and a url like https://mygitlab.com for users to hit.

1. Users are not allowed to authenticate to the API url.
2. Services are not allowed to authenticate to the base url.
3. So when clicking urls to goto repos in Sourcebot, GitLab gives could not authenticate errors.

Proposal:
Add an optional config for gitlab provider of webUrl to match the name in the DB.

@claude open a PR that adds an optional webUrl field to the GitLab config schema. The webUrl field should be used to derive the projectUrl in repoCompileUtils.ts. Minimize the amount of comments that you add.

Task: Add optional webUrl field to GitLab config

• Add webUrl to the GitLab connection JSON schema (schemas/v3/gitlab.json)
• Regenerate schema types (hand-applied, see note below)
• Use webUrl to derive projectUrl in repoCompileUtils.ts
• Update CHANGELOG
• Commit & push

Summary

Added an optional webUrl field to the GitLab connection config. When set, it's used to build repository links (projectUrl → repo webUrl and zoekt.web-url) in packages/backend/src/repoCompileUtils.ts, while url continues to be used for API calls, avatars, and clone URLs. It defaults to the value of url when omitted, so existing configs are unaffected.

const webUrl = (config.webUrl ?? hostUrl).replace(/\/+$/, '');
// ...
const projectUrl = `${webUrl}/${project.path_with_namespace}`;

This resolves the case where a self-hosted GitLab serves the API from one host (e.g. https://api.mygitlab.com) and the web UI from another (e.g. https://mygitlab.com).

Files changed:

• schemas/v3/gitlab.json — added the webUrl property.
• packages/backend/src/repoCompileUtils.ts — derive projectUrl from webUrl.
• Generated schema outputs (packages/schemas/src/v3/{gitlab,connection,index}.{schema,type}.ts and docs/snippets/schemas/v3/*.mdx) — updated to include webUrl.
• CHANGELOG.md

Note: I could not run yarn workspace @sourcebot/schemas generate (dependency install / node execution require approvals that aren't granted in this environment), so the auto-generated schema files were updated by hand to match what the generator would produce. It'd be worth running yarn workspace @sourcebot/schemas build locally to confirm the generated output is identical before merging. The CHANGELOG/PR reference #1457 as the anticipated PR number; adjust if it differs.
