[Feat]: Handle spaces in REST query URLs

[lanedsmu]

Many APIs require URLs with spaces in them, like the Microsoft graph API:
https://graph.microsoft.com/v1.0/devices?$filter=displayName eq 'computername'

Lowcoder doesn't allow these spaces, if they aren't URLencoded:

Encoding those spaces works nicely:
https://graph.microsoft.com/v1.0/devices?$filter=displayName%20eq%20'computername'

but this reduces the readability of the URL in the UI, and it requires an extra step that isn't required in development tools like cURL, Postman, or regular web browsers.

Suggestion: urlencode spaces transparently within Lowcoder, rather than requiring the user to do so explicitly.
