fix(user-actions): close asset and HTTP pending lifecycles (#166)

## Description

Fixes two regressions in the recent user-action lifecycle work:

- Asset loads now emit pending start/end lifecycle signals instead of a
single activity pulse, so long-running asset loads keep a user action
alive until the load completes.
- Tracked HTTP requests now finish their span/pending-operation
lifecycle correctly when callers use `HttpClientRequest.done` or
`abort()`.

## Related Issue(s)

Related to recent 0.12.0 user-action regressions.

## Type of Change

- [x] 🛠️ Bug fix (non-breaking change which fixes an issue)

## Checklist

- [x] I have made corresponding changes to the documentation
- [x] I have added tests that prove my fix is effective or that my
feature works
- [x] I have updated the CHANGELOG.md under the "Unreleased" section

## Screenshots (if applicable)

Not applicable. This change is internal SDK lifecycle logic, not a
visual UI change.

## Additional Notes

Focused regression coverage was added for:

- long-running asset loads keeping user actions alive until completion
- `HttpClientRequest.done` finishing the tracked span lifecycle
- `HttpClientRequest.abort()` ending the tracked span with error status
