fix(ci): set NODE_OPTIONS on the unit-shard step and prune stale eslint suppressions

The previous heap bump only touched test:unit:ci:shard, i.e. the node the shard
script spawns. The process that actually runs out of memory is the `c8` wrapper
around it — it aggregates ~577 MB of raw V8 coverage JSON — so the ceiling stayed
at the V8 default (~4 GB) and the shards kept aborting at ~4083 MB, byte for byte
the same failure. Setting NODE_OPTIONS on the step covers c8 and every child,
which is the pattern the coverage-merge job already uses.

Also prunes three eslint suppression entries whose violations no longer exist:
videoBridgeContactSheet.ts and videoBridgeRuntime.ts (no-unused-vars, fixed
during this cycle) and cli-oneproxy-commands.test.ts (no-explicit-any 14 -> 13,
a consequence of restoring the real mock in that test). Stale entries make
`npm run lint` exit 2 with 'There are suppressions left that do not occur
anymore'. Pruned and verified on an uncontaminated checkout, not the devbox.
