[RFC PATCH proxmox-backup] ui: always use arrays for 'delete' property

[Dominik Csapak <d.csapak@proxmox.com>]

In PBS we always expect an array for deletable properties, never a
comma-separated string. The code that assembles this in the gui this was
carried over from PVE where we often use those.

Instead of working around in every place where we use `delete_if_default`,
simply change the implementation to always use arrays.

Our input panel should always generate an array when having multiple
'delete' properties anyway (see 'assemble_field_data' in Utils.js) so
this could only happen if 'delete_if_default' is called when exactly one
field itself sent a 'delete: field-name' value.

sending as RFC because i might have overlooked something here.
This is an alternative to Christians patch here:
https://lore.proxmox.com/pbs-devel/20260623100525.69448-1-c.ebner@proxmox.com/T/#u

i omitted the 'fixes' tag for the specific issue the forum fixes since
it does quite a bit more than that...

feel free to add it on apply or tell me to send a new version with it,
if it's preferred to have that ;)
