feat: implement reorg audit remediations (#4682)

### Description

Bump up .registryrc and update agent configs with updated chain metadata
including:
- reorg periods
- technical stack

Updates originally made in
https://github.com/hyperlane-xyz/hyperlane-registry/pull/276

Relies on `objMerge` to be fixed
https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/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
