fix(sharing): match regular load policy on shared workflow validation

Switch to raw workflow_json fallback when Zod validation fails,
matching the policy at scripts/app.ts:1191-1198. Share service no
longer validates directly — loadGraphData applies the same fallback
under Comfy.Validation.Workflows, removing the cross-path policy
inconsistency.

Drops the tolerantArray combinator and per-field linearData.inputs
relaxation added earlier in this PR. Zod schemas stay strict as the
canonical spec; tolerance lives at the consumer boundary.

Fixes the reported share=21e32125c692 load failure and any future
extra.* shape drift, not just linearData.inputs.
