fix: handle existing RHOAI operator on a different channel

When an older RHOAI version is already installed on a different channel,
OLM can't find an upgrade path and the subscription stays stuck on the
old CSV. Detect channel mismatch and delete the old subscription/CSV
before applying the new one. Also use currentCSV instead of installedCSV
to avoid reading stale status after deletion.
