#30461
This PR contains the changes for the happy path.
On a separate PR we will be adding tests and further fixes for edge
cases.
- [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.
- [ ] Added/updated automated tests
- [x] Manual QA for all new/changed functionality
- For Orbit and Fleet Desktop changes:
- [ ] Make sure fleetd is compatible with the latest released version of
Fleet (see [Must
rule](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/workflows/fleetd-development-and-release-strategy.md)).
- [ ] Orbit runs on macOS, Linux and Windows. Check if the orbit
feature/bugfix should only apply to one platform (`runtime.GOOS`).
- [ ] Manual QA must be performed in the three main OSs, macOS, Windows
and Linux.
- [ ] Auto-update manual QA, from released version of component to new
version (see [tools/tuf/test](../tools/tuf/test/README.md)).

## Summary by CodeRabbit
* **New Features**
* Added support for TPM-backed host identity certificates enabling
hardware-backed HTTP signature authentication for hosts.

contract types.
* **Bug Fixes**
* Enhanced authentication logic to verify consistency between host
