[OPIK-7183] [FE] fix: land workspace clicks on the Projects tab

[awkoy]

Details

Clicking a workspace dropped the user into their last-visited project instead of the workspace overview. Per the Netflix customer request, a workspace click should always land on the workspace Projects tab for a consistent, discoverable entry point.

All workspace-click entry points route through HomePage (/$workspaceName/home), which branched on the stored last-visited project and redirected into it when present. This PR removes that branch so the workspace home always redirects to /$workspaceName/projects.

• HomePage.tsx — always navigate({ to: "/$workspaceName/projects" }); dropped the now-unused activeProjectId / isProjectLoading reads (also removes a brief loader flicker while the project resolved).
• router.tsx — updated the stale route comment.

Last-visited-project state is still tracked (the "Back to " button and sidebar highlighting keep working) — it is simply no longer auto-opened on a workspace click. Flows that intentionally deep-link to a project (BackToProjectButton, ProjectSelector) bypass HomePage and are unaffected.

AI-WATERMARK

AI-WATERMARK: yes

• Tools: Claude Code
• Model(s): Claude Opus 4.8
• Scope: full implementation (single-choke-point redirect change) with human direction
• Human verification: manual E2E in the browser (comet mode)

Testing

Ran the frontend in --mode comet against dev.comet.com in the yaroslav-boiko workspace, with a last-visited project set ("Demo chatbot", confirmed by the "Back to Demo chatbot" link):

• Direct workspace URL (/opik/yaroslav-boiko) → redirects to the Projects tab, not the last-visited project.
• In-app "Workspace" click from inside the Demo chatbot project → lands on the Projects tab; the "Back to Demo chatbot" link remains, confirming last-visited state is preserved but no longer auto-opened.
• npm run typecheck and eslint on the changed files — both clean.

Documentation

N/A — navigation behavior change; no user-facing docs affected.
