Subject: [PATCH] feat(host_reporter): add
 LUMERA_SUPERNODE_DISABLE_HOST_REPORTER test affordance

Allow disabling the on-chain host_reporter service via the
LUMERA_SUPERNODE_DISABLE_HOST_REPORTER=1 env var so devnet/CI test
scenarios can drive MsgSubmitEpochReport directly without losing the
account-sequence race against the SN's own ~5s auto-submit ticker.

Production deployments must leave this unset; the canonical path is
unchanged when the env var is absent.

This unblocks the everlight devnet test's STORAGE_FULL transition
scenarios (S2.3-S2.6) which submit audit reports from the SN reporter
key as part of a black-box state-machine test.
