Budi 9011 - DecodeId helper

[mikesealey]

Description

Carbon copy of packages/backend/backend-core/src/sql.utils.ts line 125 - this PR surfaces a Handlebars Helper to allow the user to un-encode a numeric ID from an SQL table. This is useful when fetching IDs from Form Blocks.

Addresses

#15428

Screenshots

When using the ID from the Form Block in the bindings, it is returned as an encoded array %5B /* ID HERE */%5D, but with this new helper decodeId we can extract the ID itself without any URI encoded square-brackets.

• Black is the unprocessed ID from the form block {{ New Form Block.actor._id }}
• Red is the new decodeId {{ decodeId New Repeater Block.actor._id }}
• Blue is the existing decodeURI helper {{ decodeURI New Repeater Block.actor._id }}

Helper also returns a comma-separated string, when passed an array of numeric IDs.

• Black is original, unprocessed array of numeric IDs %5B1%2C2%2C3%5D
• Red is the new decodeId{{ decodeId "%5B1%2C2%2C3%5D" }}
• Blue is the existing decodeURI {{ decodeURI "%5B1%2C2%2C3%5D" }}

Looks good! Only thing that would be helpful is to add a test case or two for this into the string-templates test cases!

I would test both invalid cases (passing strings that simply are not an encoded ID, as well as properly encoded IDs).
