op/doma: rename celestia relay to op-alt, add mainnet op-alt relay, vendor mainnet rollup.json

- Rename doma testnet relay from celestia to op-alt (ghcr.io/celestiaorg/op-alt-da)
- Add op-alt relay for doma mainnet with image tag 0.15.0 (not v0.15.0)
- Vendor complete mainnet rollup.json with alt_da (GenericCommitment)
- Fix per-network relay settings: namespace + CELESTIA_*_RPC env vars
- Switch mainnet op-geth to use vendored rollup.json (bind-mounted)
