User facing:
When a FLUX main model is selected, users may now add Regional Reference Image layers.
When switching between FLUX Redux and FLUX IP Adapter, the settings will change to match the model type. (IP Adapter has weight, begin/end step, but Redux does not.) The image will be retained when switching between the two.
Otherwise it works the same way as IP Adapter - both in Global and Regional Reference Image layers.

Internal state handling:
Slightly awkward, but it was easiest to make FLUX Redux a second type of IP Adapter in redux state.
Global and regional reference images still have a single `ipAdapter` field, but it can have a type of `ip_adapter` or `flux_redux`.
Ideally, this field is called `config` or `settings` or something, but we are past that point. We _could_ do a migration to rename it, but I don't think it's worth the effort.

Other changes:
- Updated canvas layer validators to handle FLUX Redux.
- Updated model list loading logic to un-set FLUX Redux models in Canvas if they are not in the list (e.g. if the user deletes the model in the main app).
- Updated graph builders - new `addFLUXRedux` util & updated `addRegions` util.
- Updated the `buildModelsHook` util to return a hook that accepts a filter callback. This handles a discrepancy: FLUX IP Adapter does not support regional guidance, but FLUX Redux does. The Regional Guidance settings provide the filter to filter out FLUX IP Adapter models from the combined list of IP Adapter ahd Redux models.
This follows the same pattern for IP Adapter w/ its CLIP Vision model. The SigLIP model is unlikely to ever change and we don't want to force the user to select it anywhere. Hardcoding it is safe and makes the UX much nicer.
The alternative is a model dropdown that will likely only ever have one valid choice in it.
- We don't need to copy the init file. Just crawl the custom nodes dir for modules and import them all. Dunno why I didn't do this initially.
- Pass the logger in as an arg. There was a race condition where if we got the logger directly in the load_custom_nodes function, the config would not have been loaded fully yet and we'd end up with the wrong custom nodes path!
- Remove permissions-setting logic, I do not believe it is relevant for custom nodes
- Minor cleanup of the utility
There's a pydantic thing that causes the graphs to fail validation erroneously. Details in the comments - not a high priority to fix but we should figure it out someday.
This method simply sets the `opened_at` attribute to the current time.
Previously `opened_at` was set when calling `get`, but that is not correct. We `get` workflows often, even when not opening them. So this needs to be a separate thing
Get the counts of workflows for the given tags and/or categories. Made a separate method bc get_many will deserialize all matching workflows, which is unnecessary for this use case.
