fix(ui): remove duplicate audit links from agent overview (#17867)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The agent detail page shows an overview of one agent in the board UI
> - The streamlined shell shows the agent contextual sidebar beside this
page
> - The sidebar has an Audit group with Activity, Runs, Costs, and
Budgets links
> - The overview also ends with an Audit card grid that has the same
four links
> - The duplicate links add noise and make the overview longer with no
benefit
> - This pull request removes the Audit card grid from the agent
overview
> - The benefit is a shorter overview with one clear place for audit
navigation

## Linked Issues or Issue Description

**What existing behavior does this improve?**

The agent overview page shows a section of Audit link cards at the end
of the page.

**Current behavior**

The overview shows four cards: Activity, Runs, Costs, and Budgets. Each
card opens the company audit page, filtered to the agent. The agent
contextual sidebar shows the same four links. Both use
`agentScopedAuditHref`. #12746 added the sidebar links. #12747 added the
overview cards in the same PR stack.

**Proposed behavior**

Remove the overview cards. Keep the sidebar Audit group as the single
entry point.

**Reason and benefit**

Operators see each audit link one time. The overview stays focused on
agent status and recent tasks.

## What Changed
- Remove the Audit card grid from the agent overview in
`ui/src/pages/AgentDetail.tsx`.

/>


## Verification

- Run `pnpm --filter ./ui exec tsc --noEmit`. The result is clean.
- Run `pnpm --filter ./ui exec vitest run src/pages/AgentDetail`. All 7
files and 56 tests pass.
- Run `pnpm check:token-gates`. All gates are clean.
- Manual check: opened an agent overview page. Made sure that the Audit
cards are not at the end of the page. Made sure that the sidebar Audit
links still open the agent-filtered audit pages.

## Risks
- Low risk. The change only removes UI markup.
- The agent-scoped audit routes and the legacy URL redirects do not
change.
- Operators who used the overview cards must use the sidebar Audit
links.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used
- Anthropic Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code. The
model used tool use, code search, git history inspection, and local test
execution. Reasoning mode: adaptive thinking.
