## Issue
Resolves#50528.
## Description
On the My device > Self-service page, with a category selected and a
search query typed, the "Install all" button previously ignored the
search: it counted (and queued) every uninstalled item in the category,
including software the search had filtered out.
This PR scopes the button — count *and* install target — to the visible
subset:
- **Backend:** `POST /device/{token}/software/install_all` now accepts a
`query` param. It's threaded through
`SelfServiceInstallAllSoftwareTitles` → `GetSoftwareTitlesForInstallAll`
→ `opts.ListOptions.MatchQuery` on `ListHostSoftware`, reusing the same
LIKE-on-`software_titles.name` semantics as the self-service list
endpoint.
- **Frontend:** new `filterSoftwareByQuery` helper layers on top of the
category filter to drive `uninstalledCount` / `hasInProgress` and the
value sent to install_all. Empty queries are stripped so the API isn't
called with `?query=`.
`display_name` matching is deliberately out of scope — the search filter
across BE list, desktop table, and mobile filter is all raw-`name`-only
today, so broadening install_all alone would re-introduce a similar
mismatch. Filed as a follow-up: #50750.
## Screen recording
In recording:
- (FE fix) showing that the UI is filtering out install all count to be
only what's on the screen
- (BE fix) showing that the call to the API only queues up the install
all for the installers shown on the screen when clicked

## Testing
- FE unit tests: `filterSoftwareByQuery` helper, `SelfServiceCard`
count-with-query + POST-with-query, `InstallAllInCategoryButton` prop
forwarding.
- BE unit test: EE service forwards the match query to the datastore.
- BE datastore test: query, category+query, empty-match cases.
- BE integration test: new "scopes to the query parameter when provided"
subtest in `TestInstallAllSelfServiceSoftware`.
- [x] Added/updated automated tests
- [x] QA'd all new/changed functionality manually

## Summary by CodeRabbit
* **Bug Fixes**
* “Install all” now respects the active self-service search query.
* Counts, progress indicators, and installation requests now reflect
only software matching the current search and category filters.
* Empty or whitespace-only searches continue to include all software in
the selected category.
