Expand sandbox callback bridge allowlist to cover the documented heartbeat surface (#5324)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - When an agent runs in an e2b sandbox or other non-managed
environment, it talks back to the Paperclip server through a per-lease
callback bridge that proxies HTTP requests
> - The bridge has an allowlist of method/path patterns it will forward;
anything outside the list is rejected to keep the bridge tight
> - The allowlist had drifted behind what the heartbeat documentation
describes as the supported callback surface — several documented
endpoints (issue updates, agent-side log emit, work-status writes) were
being rejected at the bridge
> - This pull request expands the allowlist to cover the documented
heartbeat surface and adds tests that pin every newly-allowed pattern,
so the doc and the bridge stay in sync
> - The benefit is sandboxed runs no longer hit "method not allowed" /
"path not allowed" rejections on the documented set of callbacks

## What Changed

- `packages/adapter-utils/src/sandbox-callback-bridge.ts`: expand the
method/path allowlist to match the documented heartbeat callback surface
- `packages/adapter-utils/src/sandbox-callback-bridge.test.ts`: add
coverage for every newly-allowed pattern, plus negative cases for
patterns that should still be rejected

## Verification

- `pnpm vitest run --no-coverage --project @paperclipai/adapter-utils`
- `pnpm typecheck` clean
- Manual: previously-rejected callbacks from sandboxed runs now succeed
end-to-end

## Risks

Low. The allowlist only grows; nothing previously allowed is now
blocked. Tests pin both the new allowed patterns and that out-of-doc
patterns stay rejected.

## Model Used

Claude Opus 4.7 (1M context)

## Checklist

- [x] I have included a thinking path that traces from project context
to this change
- [x] I have specified the model used (with version and capability
details)
- [x] I have checked ROADMAP.md and confirmed this PR does not duplicate
planned core work
- [x] I have run tests locally and they pass
- [x] I have added or updated tests where applicable — new tests cover
added patterns + still-rejected negatives
- [x] If this change affects the UI, I have included before/after
screenshots — N/A (no UI)
- [x] I have updated relevant documentation to reflect my changes
- [x] I have considered and documented any risks above
