feat: implement reorg audit remediations

[paulbalaji]

Description

Bump up .registryrc and update agent configs with updated chain metadata including:

• reorg periods
• technical stack

Updates originally made in hyperlane-xyz/hyperlane-registry#276

Relies on objMerge to be fixed #4678

Drive-by changes

• remove extraneous overrides + bring exiting relayer env vars into config
  • so it's in the image build directly, and we minimise break-glass-in-case-of-emergency overrides to the stateful set
• ensure txOverrides are only included if defined in infra or registry
  • ensure we delete txo verrides from the read-in config, before merging with the generated config
