test: add envfile parser coverage

[abhay-dev2901]

What does this PR do?

Adds unit test coverage for the .env parser helper used by environment variable import flows.

The tests cover parsing with = and : separators, whitespace trimming, quoted values, values containing separators, ignored
malformed/comment lines, and empty values.

Test Plan

Ran the targeted test file:

bun vitest run src/lib/helpers/envfile.test.ts

Ran the full unit test suite:

bun run test:unit

Both passed.

Greptile Summary

This PR adds 9 unit tests for src/lib/helpers/envfile.ts and simultaneously fixes a bug where .replace(/['"]+/g, '') was stripping every quote character anywhere in a value (e.g. O'Brien → OBrien). The fix replaces it with an anchored backreference regex (/^(['"])(.*)\1$/) that only removes a matching surrounding quote pair. All previously-flagged gaps (CRLF line endings, mid-value quotes) are now covered by the new test suite.

Confidence Score: 5/5

Safe to merge — the implementation fix is correct and all tests accurately reflect the new behaviour.

No P0 or P1 issues found. The regex change is logically sound, the test expectations are correct against the updated implementation, and the CRLF case is handled correctly because trim() strips the trailing
from values before the regex is applied.

No files require special attention.
