[code-enhancement] server side decoding approach for datasource name < or > characters-decode issue

[shah21]

Is your proposal related to a problem?

"<>" are stored as "< >" in the database. So, instead of decoding the value from the frontend everywhere it is used, can we decode it from the API itself and send it to the client?

NOTE
We need to test this solution with the datasource, data-queries, and code hinter test cases first before proceeding with this code change.
