fix: resolve srs ingestion bug, cfg verification, & return error messages in response body

Changes proposed

• Fix SRS ingestion bug which was causing blobs greater than 1.2 mb to fail to verify. This required retuning the kzg loader to intake the entire G1 SRS with the number of points read being proportional the max blob size (i.e,max_blob_bytes / 32) to specify the max number of field elements.
• Update config verification with more verbose invariants and unit tests.
• Added test that tests known failure case in existing EigenDA batcher where identical merkle inclusion proof are generated for blobs in the same batch with identical contents.
• removed use of assert in favor of require for more standardized testing.
• added test to assert that a blob of 2MB can be successfully dispersed and verified.
