Backend changes for Apple BYOD (personal) MDM enrollment.
- Adds a `byod` enrollment path that distinguishes personal devices from
organization-owned devices.
- Persists per-host Apple MDM enrollment access rights in a new
`host_mdm_apple_enrollment_permissions` table so SCEP/ACME renewal
honours Apple's monotonic-narrowing invariant (permissions can never be
widened on profile replacement).
- Surfaces wipe/lock/clear-passcode allowed flags on host details for
manually-enrolled Apple hosts.
- Renames the personal enrollment status label to `On (manual -
personal)`.
# Checklist for submitter
If some of the following don't apply, delete the relevant line.
- [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.
- [x] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements), JS
inline code is prevented especially for url redirects, and untrusted
data interpolated into shell scripts/commands is validated against shell
metacharacters.
- [x] If paths of existing endpoints are modified without backwards
compatibility, checked the frontend/CLI for any necessary changes
## 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)
- [ ] QA'd all new/changed functionality manually
### Test plan
- Manual (profile) enrollment, company-owned: device receives full
access rights; wipe/lock/clear-passcode allowed.
- Manual (profile) enrollment, personal (BYOD via `byod=1`): device
receives narrowed access rights (no device lock/erase); host details
show wipe/lock/clear-passcode disabled.
- SCEP/ACME renewal for each of the above: renewed profile preserves the
original ServerURL (incl. `byod=1`) and the stored (narrowed) access
rights; Apple does not reject the replacement.
- Renewal batching: multiple company-owned hosts collapse into a single
InstallProfile command; a BYOD host gets its own command.
- Account-Driven User Enrollment (ADUE): enroll a personal device via
ADUE and confirm it is inherently restricted (Apple `UserEnrollment`
mode — no device lock/erase regardless of AccessRights), and that its
SCEP renewal succeeds and preserves the account-driven enrollment
profile.
- Deleted-then-returned device: delete a still-enrolled BYOD host in
Fleet, let it check back in, and confirm a subsequent SCEP renewal still
uses the narrowed permissions.
## 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`).

## Summary by CodeRabbit
* **New Features**
* Added personal (BYOD) Apple MDM enrollment support across manual
profiles, OTA enrollments, and SCEP/ACME certificate renewals, with
access rights generated appropriately.
* Apple host details now surface per-device permission flags for wipe,
lock, and clear passcode when available.
* Enrollment status text now shows personal manual enrollments as “On
(manual - personal)”.
* **Bug Fixes**
* Enforced remote wipe/lock (and clear passcode) permissions correctly
for personal devices, including persistence across renewals.
* Host deletion cleanup now removes newly tracked enrollment permission
data.
