Handle valid non-object JSON before adding "hex".

data.read() succeeds for arrays and other non-object JSON values. data.pushKV("hex", ...) then throws because UniValue::pushKV() requires VOBJ. Use !data.read(...) || !data.isObject() and add a regression test for an array root.

In `@src/governance/common.cpp` around lines 59 - 65, Update the data parsing
logic around UniValue data so the fallback also runs when read succeeds with a
non-object root: validate both read success and data.isObject() before calling
pushKV. Preserve the existing plain-text fallback and ensure the hex field is
added only to an object; add a regression test covering an array-root JSON
input.

Add targeted governance JSON tests.

  • Cover object-root, array-root, and unparsable data in Object::ToJson().
  • Cover all CGovernanceManager::ToJson() totals, including objects_total, per-type counts, erased, and votes.
  • Cover all four fields returned by GetVotesJson() for at least one vote signal.

Existing functional tests cover only normal object data and selected funding vote counts.
