Refactor Websocket server parser to support space char in values

[lucifercr07]

Description

• Ref: https://github.com/DiceDB/dice/issues/1029#issuecomment-2435065742
• For string value with a space (e.g., "name":"New York"), the command parsing and argument splitting in the command parser for websocket server, does not handle this scenario correctly.
• Refactor parser to handle such scenarios
• We can refer to httpServer parser for references.

Tasks

• Refactor websocket server command parser to support space char as key values.
• Add tests for the given scenario.

I have a small question here: Should the key and value both be able to handle in-between spaces or is it only for the value?
