Integrates upstream PR OpenBankProject#2781 (BulkPayment, Qualified Identifier scheme,
PayeeLookup updates, dep-check suppressions for Hydra/Avro, dep bumps
for jackson-databind, mssql/mysql, elasticsearch, grpc/netty).

Auto-resolved pom.xml conflicts by keeping the higher dep version on
each line:
- com.mysql:mysql-connector-j 9.4.0 -> 9.7.0 (theirs)
- com.microsoft.azure:msal4j 1.16.2 -> 1.24.1 (theirs)
- elastic4s-client-esjava: com.sksamuel:8.11.5 -> nl.gn0s1s (theirs;
  upstream migration to the community fork, same package names)
- bcpg/bcpkix 1.84, postgresql 42.7.11, log4j 2.26.0,
  commons-beanutils 1.11.0, nimbus-jose-jwt 10.5, oauth2-oidc-sdk
  11.37.1, grpc 1.75, async-http-client 2.15.0 — kept (ours, higher).

Our v6.0.0 Http4s600.scala is untouched by the merge. Build + obp-api
smoke (BankTests, PasswordResetTest, v5 RootAndBanksTest) pass.
