Subject: [PATCH] fix(db test): resolve absolute paths before computing
 relative path

when running supabase db test from a docker-outside-of-docker environment,
test file paths may be absolute host paths while utils.DbTestsDir is relative.
filepath.Rel fails when the base path is relative and the target is absolute.

this change converts both paths to absolute before computing the relative path,
which handles all path combinations correctly: relative+relative, absolute+absolute,
and mixed scenarios like docker-outside-of-docker.

closes #3194
