Enhancement: add label formatting for dynamic-list customapi widget

[rayanmestiri]

Proposed change

This adds the capability to format the label in dynamic-list for the customapi widget. The options are the ones already available : text, number, float, percent, duration, bytes, bitrate, size, date and relativeDate.

There wasn't an open specific feature request for this but I figured I must not be the only one who wants this since I noticed interest in comments of this one : #4906 (comment).

I was going to make it for myself anyways so I thought I might as well share it. I know it isn't technically allowed in the guidelines to not have a linked feature request, so feel free to reject this PR for this reason.

I chose to parse the format parameter at the same level as label to keep it consistent with the rest of the display config options.

Type of change

• New service widget
• Bug fix (non-breaking change which fixes an issue)
• New feature or enhancement (non-breaking change which adds functionality)
• Documentation only
• Other (please explain)

Checklist:

• If applicable, I have added corresponding documentation changes. See customapi.md changes
• If applicable, I have reviewed the feature / enhancement and / or service widget guidelines.
• I have checked that all code style checks pass using pre-commit hooks and linting checks.
• If applicable, I have tested my code for new features & regressions on both mobile & desktop devices, using the latest version of major browsers.

Thanks

ps. Technically this supports other things too now besides format…

Indeed, I admit I could have been a bit more thorough with it. It should enable support for remap, scale, prefix and suffix. I did not test with these properties but I can do some QA. If all is good, do you want me to open a PR to update the docs ?
