Matt Morley dbd6eea4e9 Cache requested calibration format outside of state store (#2310)
## Description

On main, this pop-up lists the wrong resolution. The index in the state
is getting updated out from underneath us. The easiest solution I have
is to just cache this number.

/>

Not sure of a great way to test this, since it requires the backend
taking calibration snapshots

## 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
