test: cover GetHTTPPath branches

[devsy-app]

Package reviewed

pkg/gitcredentials (SSH/git/credentials category)

Issue found

GetHTTPPath had zero test coverage despite being a production code path
used by pkg/agent/tunnelserver to resolve host git credentials
(tunnelserver.resolveHostGitCredentials). It has three distinct branches plus
an error path, none of which were exercised:

1. CurrentPath provided → returned as-is (short-circuit).
2. useHttpPath not set/disabled → returns "".
3. useHttpPath = true → parses the workspace repository URL and returns the
   path component.
4. Invalid repository URL → returns a parse workspace repository error.

Change

Added 6 focused tests for GetHTTPPath in pkg/gitcredentials/gitcredentials_test.go,
mirroring the existing test style (temp HOME + .gitconfig via GIT_CONFIG_NOSYSTEM):

• TestGetHTTPPath_ReturnsCurrentPathWhenProvided — branch 1.
• TestGetHTTPPath_EmptyWhenUseHttpPathDisabled — branch 2 (default).
• TestGetHTTPPath_ReturnsRepositoryPathWhenUseHttpPathEnabled — branch 3.
• TestGetHTTPPath_EmptyPathWhenRepositoryHasNoPath — branch 3 edge: host-only URL.
• TestGetHTTPPath_ErrorOnInvalidRepositoryURL — branch 4 error path.
• TestGetHTTPPath_PerHostScopedConfigOnly — useHttpPath set for a different host
  must not apply (credential config is per protocol://host).

No behavioral change — test-only addition. Repeated string literals extracted to
constants to satisfy goconst in CI lint.

Verification performed

• task cli:format — clean.
• task cli:lint:ci — 0 issues.
• task cli:test — pkg/gitcredentials passes (ok ... coverage: 60.3%).
  The only failure is pkg/git (TestRepoClone*), a known pre-existing stale
  assertion on origin/main unrelated to this change (this PR does not touch
  pkg/git).
