fix: expose raw deploy-branch and keep-git-dir in git:report

The bare `deploy-branch` and `keep-git-dir` keys in `git:report` returned the computed (effective) value rather than the raw per-app value, with no separate `computed-*` key to distinguish "set per-app" from "falling back to global or default". This left external tooling unable to detect a per-app unset without out-of-band state. The bare keys now hold the raw per-app value (empty when unset) and new `computed-deploy-branch` and `computed-keep-git-dir` keys hold the effective value, matching the convention used by `nginx-vhosts`, `network`, and `builder`. Closes #8610.
