improvement(fivetran): use shared filterUndefined and readonly constant lists

[waleedlatif1]

Summary

• Replace the local compactBody helper in the Fivetran tools with the shared filterUndefined from @sim/utils/object (same semantics: drops only undefined keys)
• Mark the Fivetran block's operation lists, option lists, and PAUSE_ONLY_UPDATE as const, spreading them into condition/required/options and using (X as readonly string[]).includes(op) for membership, matching the Snowflake/QuickBooks/Harmonic blocks
• No behavior change: regenerated tool metadata and docs are byte-identical

Type of Change

• Improvement / refactor

Testing

• Scoped type check of tools/fivetran and the Fivetran block
• check-block-registry vs staging; targeted audits: canvas-sentences, tool-metadata, docs, integration-catalog, utils, comment-hygiene, tool-request-boundary, tool-param-reachability
• Full type-check, check:audits, and test suite left to CI

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
