fix: use BytesN<32> for WASM hash in PendingUpgrade struct
6f43f62 
- Change ConfigKey::UpgradeRejectedAt payload from String to BytesN<32>
- Update require_no_upgrade_collision, get/set/clear_upgrade_rejected_at
  helpers to accept &BytesN<32> instead of &String
- Remove wasm_hash.is_empty() guard (BytesN<32> is always 32 bytes)
- Update 6 test usages from String::from_str hashes to BytesN::from_array

PendingUpgrade.wasm_hash was already BytesN<32> in types.rs; this fixes
the remaining String references in governance.rs that caused a type
mismatch at the host upgrade call site.

Closes solutions-plug#32
