woodpecker: disable partial clone (partial: false) — fix intermittent git exit-128

Infra pipelines were failing intermittently across all authors (e.g. #241-244,
#247) with the git clone step exiting 128:

  git fetch --depth=1 --filter=tree:0 ...   (partial/treeless clone)
  git reset --hard <sha>
  fatal: could not fetch <tree-sha> from promisor remote
  remote: 404 page not found

The plugin-git clone defaulted to a partial (treeless) clone. The initial ref
fetch carries credentials, but the lazy *promisor* object fetch triggered by
`git reset --hard` hits the PRIVATE Forgejo repo without creds -> 404 -> exit
128. Whether it fired was luck-of-the-draw, hence the ~50% intermittent failures
fleet-wide (not specific to any commit).

Fix: set `partial: false` on every clone block so all objects for the (still
shallow) commit are fetched upfront with creds — no fragile lazy promisor fetch.

Diagnosed against the woodpecker Postgres DB (steps/log_entries) since the
Woodpecker HTTP API was itself flapping. Earlier "permission for ViktorBarzin"
log lines were an unrelated cross-forge red herring.
