Normalize remaining non-Common RPC param names to camelCase in OpenRPC

[Copilot]

This PR completes the remaining RPC parameter naming cleanup by converting non-camelCase parameter names in non-Common methods to camelCase, with emphasis on non-Common namespaces (including F3 and related endpoints). It also aligns generated OpenRPC output with the updated names.

• Scope: remaining non-camelCase PARAM_NAMES

  • Updated snake_case parameter names to camelCase across:
    • auth, wallet, chain, msig, state, net, f3
  • Kept naming semantic, and expanded abbreviated names where it improved clarity:
    • start_tsk → startTipsetKey
    • end_tsk → endTipsetKey

• OpenRPC schema alignment

  • Regenerated snapshots impacted by param-name metadata changes:
    • src/rpc/snapshots/forest__rpc__tests__rpc__v0.snap
    • src/rpc/snapshots/forest__rpc__tests__rpc__v1.snap

• Representative change

  // before
  const PARAM_NAMES: [&'static str; 3] = ["address", "start_tsk", "end_tsk"];
  
  // after
  const PARAM_NAMES: [&'static str; 3] = ["address", "startTipsetKey", "endTipsetKey"];
