Fix Academic Citation Tracker agent job: recompile lock file with gh-aw v0.79.8 (#9910)

The "agent" job was failing immediately because the lock file (compiled
by `gh-aw v0.79.6`) generated a step calling
`merge_awf_model_multipliers.cjs`, but the pinned
`github/gh-aw-actions/setup@v0.80.4` did not ship that script — causing
a `MODULE_NOT_FOUND` crash before the Copilot CLI ever ran.

## Changes

- **`.github/workflows/academic-citation-tracker.lock.yml`** —
recompiled with `gh aw compile --strict` using v0.79.8; setup action is
now pinned to the matching `@v0.79.8` release which includes all
expected scripts
- **`.github/dependabot.yml`** — compiler updated ignore entries to
cover both `github/gh-aw-actions/**` (subdirectory refs like `setup`)
and `github/gh-aw-actions` (base ref), preventing Dependabot from
bumping the setup pin out of sync again
