fix(credentials): gitea arms resolve seat slots — fail loud, no silent service fallback
On a fleet host, load_credentials gitea-mosaicstack / gitea-usc now resolve
a git identity's SEAT SLOT (MOSAIC_GIT_IDENTITY with a directory under
MOSAIC_BRAIN_HOME/fleet/agents/) as the token source, mirroring
get_gitea_token in detect-platform.sh (the #1311 lineage). URL still comes
from credentials.json (provider config, not identity). A seat with an empty
or missing slot REFUSES (rc 1, identity and slot path named) rather than
falling back to the shared service store — the same no-fallback rule the
git credential helper and detect-platform enforce; a silent fallback would
act as the wrong identity (#1343 family, usc/uconnect#3084 precedent).
No identity resolved, or a non-seat identity: the service store, unchanged.
Other services untouched (no seat concept to invent).

Hermetic suite test-credentials-gitea-seats.sh (sandbox brain + sandbox
credentials.json; no real credential read), CI-reachable via
test:framework-shell. Six pins: slot-sourced token, seat-miss refusal
without fallback (token compared against the service value), no-identity
service path, non-seat identity, woodpecker indifference to the identity,
pre-set GITEA_TOKEN never overridden. Mutants killed: seat-miss-falls-back
(dies at G2), seat-reads-service-store (dies at G1).

Known pre-existing (out of scope, unchanged by this PR): this host's
credentials.json stores gitea tokens under .gitea.<inst>.default and
per-identity keys, while the loader reads .gitea.<inst>.token — the
no-identity service path fails identically before and after this change
(verified against origin/next's loader). Filed for the wrapper-defect
batch rather than widened here.

# Hermetic regression for load_credentials gitea seat-slot resolution.
# Sandbox brain home + sandbox credentials.json; no real credential is read.
#
# Pins:
# G1 MOSAIC_GIT_IDENTITY naming a seat with a populated slot → GITEA_TOKEN
# comes from the SLOT, URL from credentials.json.
# G2 seat with an EMPTY slot → rc 1, refusal names the identity and the
# slot path, and NO fallback to the service store occurred (the token
# must not equal the service-store value).
# G3 no identity → service store, unchanged behavior (token from
# credentials.json).
# G4 identity that is NOT a seat (no directory) → service store (same as
# G3; the identity is irrelevant on a non-fleet path).
# G5 other services are untouched: woodpecker resolution works the same
# with and without MOSAIC_GIT_IDENTITY set.
# G6 pre-existing GITEA_TOKEN env is never overridden by the seat path.
