Disable AI models for 2D and ND datasets

[hotzenklotz]

Context

Our AI models are configured and tuned for 3D EM datasets. It does not work well on 2D datasets (and was never intended for those).

Example segmentation of some 2D dataset:

See https://scm.slack.com/archives/CMBMU5684/p1721985399703099?thread_ts=1721318145.073349&cid=CMBMU5684

Expected Behavior

Probably add some validation before launching any of the AI features. 2D and ND datasets should probably be denied from running any AI inference.

Perhaps also include guards against weird datatypes, e.g. uint24. IIRC, the AI inference only works with uint8 (please double-check).

Have a look at the "Create Animation job" modal. That includes validation against 2D and ND datasets.

Current Behavior

The AI job runs on the 2D dataset but the output is not useful. All voxels were merged into one segment per chunk and agglomerated into one single segment.

Steps to Reproduce the bug

• Cannot reproduce the bug anymore / needs deeper investigation.

See https://scm.slack.com/archives/CMBMU5684/p1721985399703099?thread_ts=1721318145.073349&cid=CMBMU5684

Your Environment for bug

• Version of WEBKNOSSOS (Release or Commit): Version: 28878 (Server is currently at 28881!)
• Specific to long-running jobs (set jobsEnabled=true in application.conf)
• Specific to webknossos.org (set isDemoInstance=true in application.conf)

Are there any more features than those that can be accessed via the "AI Analysis" button? Would it work if I simply disable said button with a fitting tooltip or should the button disappear for 2D and ND datasets?

note to self: button shouldnt disappear. maybe disable for 2D/ND and throw error on start for weird units
