fix(studio): point agent Open traces button to Intake traces

[walston]

Summary

The "Open traces" button on the agent detail page navigated to the Monitor tab (/agents/monitor) and was gated behind MONITOR_ENABLED, so with Monitor disabled it was hidden entirely. It now navigates to the Intake Traces route (/intake/traces) and is gated behind INTAKE_ENABLED, so it renders and links to Traces as intended.

Changes

• AgentDetailRoute/index.tsx: swap getAgentMonitorRoute → getIntakeTracesRoute and MONITOR_ENABLED → INTAKE_ENABLED for the "Open traces" button, and use the ListTree icon to match the AppBar Traces nav item (was Activity).
• AgentDetailRoute/index.test.tsx: stub VITE_FF_INTAKE_ENABLED, and add a test asserting the button navigates to the Intake traces route.

Type of Change

• Code change (feature, bug fix, or refactor)
• Code change with documentation updates
• Documentation only
• Contributor tooling or automation
• CI, build, or test infrastructure

Quality Gates

• Tests added or updated for changed behavior
• Existing tests cover changed behavior — justification:
• Tests not applicable — justification:
• Documentation updated for user-visible behavior
• Documentation not applicable — justification: internal navigation link fix; no user-facing docs describe this button target.

Verification

• Pull request title follows the repository's Conventional Commit format
• Every commit includes an appropriate Signed-off-by: trailer
• uv run pre-commit run -a passes, or any blocked checks are identified below
• Targeted tests pass, or tests are marked not applicable above
• No secrets, API keys, or credentials are included

Targeted validation:

• pnpm --filter nemo-studio-ui exec vitest run src/routes/agents/AgentDetailRoute/index.test.tsx → 4 passed (incl. new navigation guard).
• pnpm exec prettier --check on changed files → clean.
• pnpm exec eslint on changed files → clean.
• pnpm --filter nemo-studio-ui run typecheck → clean.
• Commit-time pre-commit hooks (incl. DCO) passed on the changed files. Full uv run pre-commit run -a not run; change is web-only, and CI runs the full gate.
