fix: correctly search for verified domain (#8820)

# Which Problems Are Solved

Searching orgs by domain currently only looked for the primary domain,
but should be possible with all verified domains (as documented)

# How the Problems Are Solved

- fixed the search query

# Additional Changes

None

# Additional Context

- closes https://github.com/zitadel/zitadel/issues/8749
