[BUG] API request timeout should always clear its timer

[utksh1]

Problem

frontend/src/api.ts clears the request timeout after fetch() resolves. If fetch() rejects or is aborted, the timeout cleanup path is skipped.

Expected behavior

The timeout should be cleared in a finally block so every request path cleans up its timer.

Acceptance criteria

• Move timeout cleanup into finally.
• Preserve the existing abort behavior.
• Add a focused unit test for rejected/aborted requests proving the timer is cleared.

Hi @utksh1, I would like to work on this under GSSoC'26 .
I’ll update the timeout cleanup to run through a finally block and add a test covering rejected/aborted requests to make sure timers are always cleared properly.
Kindly assign it to me.
