[Feature] Better ways to create new face tag/update face tag

[EmberLightVFX]

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

The feature

I have a bunch of photos that the machine learning didn't catch (eg. face too small in image, back of head showing only) or photos of pets that didn't get a match ether.

I made a PR that allows me to simply ctrl+drag to create a new face tag. I also made a companion PR that lets me ctrl+click on an already existing tag to quickly be able to change what face has bin tagged.

Before I had to go (+) -> drag the tag-square to the correct position -> resize to fit the face -> enter the person.
After the PR I simply ctrl+drag -> enter the person.
It saves a lot of clicks over many photos.

And to edit a tag I had to go Edit People -> Seach for the wrongly tagged face if there is many tagged -> Select new face -> Pick new face. After we can now simply ctrl+click on the face on the picture -> Select new face

I'm a python and c++ dev and not that familiar with svelte so I used Claude to help me structure the code but I did manual review of the code and updated parts that wasn't needed, made them more clean and more logical.
I'm super grateful that @danieldietzler took a look at it even with the Claude help but the svelte code wasn't up to par so the PRs got closed.

I think these features would be a great UX update to Immich but I would also love to know other peoples thought on this kind of feature.

If anyone that knows Svelte better than me want to take a stab at it you have my closed PRs here:
ctrl+drag to create person tag: #28386
ctrl+click to select new face on tag: #28425

Cheers!
