feat: governance cache SDK, payloads panel, and gasless voting

[JoaquinBattilana]

Summary

Migrates governance/proposal pages off the TheGraph subgraph onto the governance-v3-cache GraphQL API, adds a payloads panel with executable targets and Seatbelt links, and revives gasless voting behind a server-side Gelato relay.

Changes

Governance cache SDK

• New typed fetching layer in src/services/governance-cache-sdk/ (raw fetch + gql authoring + hand-written types) over the curated cache endpoints, plus the auto-generated/derived fields needed to fully replace the subgraph.
• React Query hooks consolidated into src/hooks/governance/useGovernanceCache.ts; query keys centralized in queryKeysFactory.governanceCache*.
• Old subgraph data path removed from governance.

Payloads panel

• New ProposalPayloads panel: per-payload chain, id, state, access level, creator, controller, executable targets, and Seatbelt report link.
• Lifecycle panel heading renamed to "Timeline"; the Seatbelt link moved into the payloads panel.
• SDK now surfaces PayloadAction[] (target/signature/callData/value/withDelegateCall/accessLevel) per payload.

Gasless voting

• New pages/api/gelato/relay.ts server route holds the Gelato sponsor key server-side (never bundled to the client) and relays via Gelato's sponsored-call REST endpoint.
• The route whitelists the target against known voting machines and requires the submitVoteBySignature selector, so sponsored gas can't be spent on arbitrary transactions.
• Client gasless path is a single step (sign EIP-712 -> relay -> poll public task status); the dead two-step approval scaffolding was removed.
• Gated by NEXT_PUBLIC_ENABLE_GASLESS_VOTING (public on/off) plus the server-side GELATO_SPONSOR_KEY; dormant unless both are set.

Notes

• Payload actions depend on the cache backend exposing the field (already live on staging).
• No new npm dependencies.
