Polish operator UI task controls (#5427)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Operators spend most of their day scanning skills, routines, inbox
groups, and activity cards
> - Several small UI rough edges made those surfaces harder to scan or
easier to crash on real API payloads
> - These fixes are grouped together because they are low-risk operator
quality-of-life improvements rather than separate control-plane
contracts
> - This pull request polishes skills metadata, routine run-now access,
grouped issue creation defaults, monitor activity rendering, and
activity row identity layout
> - The benefit is a smoother board workflow with fewer small
interruptions while keeping the change set compact

## What Changed

- Improves company skill source display and the used-by agent list.
- Truncates long skill source paths and adds a copy affordance.
- Adds a row-level run-now button to the routines table.
- Adds grouped issue creation defaults for inbox issue groups and aligns
grouped add buttons to the right.
- Fixes `IssueMonitorActivityCard` when `monitorNextCheckAt` arrives as
an ISO string.
- Polishes activity row actor avatar/name layout by using the shared
avatar primitive.

## Verification

- `pnpm run preflight:workspace-links && pnpm exec vitest run
ui/src/pages/Routines.test.tsx ui/src/components/IssuesList.test.tsx
ui/src/lib/inbox.test.ts
ui/src/components/IssueMonitorActivityCard.test.tsx` — 91 passed.
- The routines test emitted the pre-existing Radix warning about missing
`DialogTitle`/description in dialog content; tests still passed.
- Pairwise merge checks against the other two PR branches reported no
textual conflicts.

## Risks

- Low: changes are UI-focused and covered by targeted component/lib
tests.
- Low-to-medium: activity row layout changes could affect dense feed
scanability; the implementation uses the shared avatar component and
keeps truncation behavior.

> 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

- OpenAI Codex coding agent, GPT-5 model family (`gpt-5`), tool-enabled
Paperclip heartbeat environment. Context window and internal reasoning
mode are not exposed by the runtime.
