The SponsoredFPC contract address changes when aztec-nr is updated (different bytecode → different class ID → different address), which causes the genesis archive root to change and bricks nodes running a different aztec-nr version. Disabling it makes staging-public match the testnet/mainnet config, avoiding genesis root divergence across versions.

Summary
Disables the SponsoredFPC contract in the staging-public environment to prevent genesis archive root divergence across aztec-nr versions.
The SponsoredFPC contract address depends on its compiled bytecode, which changes whenever aztec-nr is updated (oracle renames, log domain separation, etc.). This causes the genesis archive root to differ between versions, bricking nodes that were deployed with a different aztec-nr version.
Setting
SPONSORED_FPC=falsealigns staging-public with testnet and mainnet configuration, which don't use SponsoredFPC.Context
