fix(dao): wire V2 cost model into proposal_create staging

Browse source 
Without staging.language_view(), pallas does not compute
script_data_hash. Chain rejects the tx with PPViewHashesDontMatch.
Same trap that plutus_mint hit on 2026-05-07 — same fix here.

Caught attempting first dao_proposal_create_unsigned on preprod_test
DAO 2026-05-07 PM after deploying governor + proposal validator ref
UTxOs via the new file-path workaround for the MCP large-string bug.
