feat: custom ci report for injector config payloads

[gosuto-inzasheru]

currently the default report fails to:

• resolve each gauge address to a more readable label
• make amounts readable (divide by decimals)
• provide a (running) total of the outgoing amounts

eg see https://github.com/BalancerMaxis/multisig-ops/pull/623#issuecomment-1806359997

ok so this has been implemented already; all three features exist in the current report
