fix: patch dedicatedFarm field for pre-V14 Farm event decoding

Existing indexer snapshots on all networks were built with an old
typesBundle that had a typo: "dedicatedFarm:" (trailing colon) in the
Farm struct. The stored JSON has "dedicatedFarm:" as the key, but the
processor expects "dedicatedFarm" (no colon) after the typesBundle was
corrected. This causes an assertion failure when decoding pre-V14
FarmStored/FarmUpdated events (specs 63-70).

Production 2.12.3 had this workaround in the isV101 branch, which was
removed by the typegen automation (PR #207) when relabeling the hash
as isV63.

The patch sets dedicatedFarm = false on the raw args before decoding.
This is safe because farmStored hardcodes dedicatedFarm = false anyway.
Remove this workaround after all indexers are resynced with the
corrected typesBundle.
