Propagate changes after modifying OD model (#2299)

## Description

<!-- What changed? Why? (the code + comments should speak for itself on
the "how") -->

<!-- Fun screenshots or a cool video or something are super helpful as
well. If this touches platform-specific behavior, this is where test
evidence should be collected. -->

<!-- Any issues this pull request closes or pull requests this
supersedes should be linked with `Closes #issuenumber`. -->

This PR adjusts how model modification is handled. Any updates to
metadata, or deletion is handled in the frontend after sending data to
the backend. Any creation of models occurs in the backend, and we push
an update to the frontend.

This PR also fixes a typo in PhotonUtils which meant we hit the wrong
endpoint when an IP was passed into the status check.

## Meta

Merge checklist:
- [x] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [x] The description documents the _what_ and _why_
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with settings back to v2025.3.2
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [ ] If this PR addresses a bug, a regression test for it is added
