fix: clean up PR diff — restore unrelated files to master state

Previous merges from master accidentally re-introduced 18 chain files
deleted upstream, and the swiftnodes additions were applied to a stale
master snapshot that dropped a number of sibling RPC entries (wss
endpoints from drpc/publicnode, dexguru explorers, etc.).

This commit:
- Deletes 18 accidentally re-introduced chain files
- Restores 71 modified chain files to current master state
- Re-applies just the SwiftNodes RPC URL to the 53 chains that should
  have it (textual insertion, no JSON re-serialization that would expand
  master's compact format)
- Runs prettier on the result

Net effect: every diff line now is either a SwiftNodes URL addition or
the trailing-comma flip on the line above it.
