For #32040.
---
Backend changes to unblock the development of the orbit and frontend
changes.
New GET and PUT APIs for setting/getting software for Linux Setup
Experience:
```
curl -k -X GET -H "Authorization: Bearer $TEST_TOKEN" https://localhost:8080/api/latest/fleet/setup_experience/linux/software?team_id=8&per_page=3000
curl -k -X PUT -H "Authorization: Bearer $TEST_TOKEN" https://localhost:8080/api/latest/fleet/setup_experience/linux/software -d '{"team_id":8,"software_title_ids":[3000, 3001, 3007]}'
```
New setup_experience/init API called by orbit to trigger the Linux setup
experience on the device:
```
curl -v -k -X POST -H "Content-Type: application/json" "https://localhost:8080/api/fleet/orbit/setup_experience/init" -d '{"orbit_node_key": "ynYEtFsvv9xZ7rX619UE8of1I28H+GCj"}'
```
Get status API to call on "My device":
```
curl -v -k -X POST "https://localhost:8080/api/latest/fleet/device/7d940b6e-130a-493b-b58a-2b6e9f9f8bfc/setup_experience/status"
```

- [X] Changes file added for user-visible changes in `changes/`,
`orbit/changes/` or `ee/fleetd-chrome/changes`.
See [Changes
files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files)
for more information.
## Testing
- [X] Added/updated automated tests
- [X] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [x] QA'd all new/changed functionality manually
## New Fleet configuration settings
- [X] Verified that the setting is exported via `fleetctl
generate-gitops`
- [X] Verified the setting is documented in a separate PR to [the GitOps
documentation](https://github.com/fleetdm/fleet/blob/main/docs/Configuration/yaml-files.md#L485)
- [X] Verified that the setting is cleared on the server if it is not
supplied in a YAML file (or that it is documented as being optional)

Fixes#31781
Only test-related changes.
I found this useful for agentic AI workflows. For example, you have an
AI agent debugging/rerunning a test. Meanwhile, you can spin up another
`mysql_test` instance in another workarea and work there in parallel.
Fixes#30458

# Checklist for submitter
- We will add changes file later.
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements)
- [x] If database migrations are included, checked table schema to
confirm autoupdate
- For database migrations:
- [x] Checked schema for all modified table for columns that will
auto-update timestamps during migration.
- [x] Confirmed that updating the timestamps is acceptable, and will not
cause unwanted side effects.
- [x] Ensured the correct collation is explicitly set for character
columns (`COLLATE utf8mb4_unicode_ci`).
- [x] Added/updated automated tests
- Did not do manual QA since the SCEP client I have doesn't support ECC.
Will rely on next subtasks for manual QA.
