Request column names from server when loading table

[SchrodingersGat]

This PR adds facility for tables to fetch the translated column names from the server, using the existing metadata endpoint. This allows us to reduce duplication of translated strings between the server and client.

As each table is constructed from data provided by a defined endpoint, and (most) API fields have localized label attributes, we can use those to render the localized table columns.

Note that the table column titles can be manually overridden if required.

If this is deemed a good idea, following improvements can be made:

• Cache the column names based on the table key
• Update existing tables to not specify column names where not required.

Looks/Sounds intresting and relativley simple to implement. Maybe caching all table column names similar to states would be a good idea?

Nice idea, LGTM now after caching is implemented.

This has now broken my machine integration tables. E.g. this API endpoint is used in a table:

https://github.com/wolflu05/InvenTree/blob/34d730febf68dc5e0851837955797e1866042f19/InvenTree/machine/serializers.py#L110
https://github.com/wolflu05/InvenTree/blob/34d730febf68dc5e0851837955797e1866042f19/InvenTree/machine/api.py#L157-L172

And PUI always shows a notification on load:

After investigation, it seems like that this is coming from:

InvenTree/src/frontend/src/functions/forms.tsx

Lines 56 to 63 in 15f58b9

	if (!actions) {
	notifications.show({
	title: t`Form Error`,
	message: t`Response did not contain action data`,
	color: 'red'
	});
	return null;
	}

Because when using an APIView for non model api endpoints this results in no actions added to the OPTIONS response.

Same things applies for the Plugin page in the Admin center.

How should we fix this?

[SchrodingersGat]

@wolflu05 you found that so quickly! I had just been looking into this. I think that we should

a) Remove the "form error - response did not contain action data" - it is a very "nerdy" error which I had in there for debugging. Probably not very useful
b) Where is the "permission denied" warning coming from?

[wolflu05]

Yes, was trying to resolve the merge conflicts on the machines branch and refactor the tables, ...

Yes, I'm on board with just removing this notification. The enduser doest know what that means. Do you create an PR for that?

Regarding the permissions error, I guess that is coming from here:

InvenTree/src/frontend/src/functions/forms.tsx

Lines 72 to 76 in ec2a66e

	if (!(method in actions)) {
	// Missing method - this means user does not have appropriate permission
	permissionDenied();
	return null;
	}
