The HTTPProxy API documentation says two hostname problems are reported in HostnamesVerified, and the controller names neither there. The condition's own True message also says every hostname is "accepted and programmed", while it checks acceptance only.

Problem	The documentation said	The controller reports it in
A hostname already programmed on another resource	HostnamesVerified	HostnamesInUse
A hostname whose DNS record is not programmed	HostnamesVerified	DNSRecordsProgrammed, since #657
A hostname that is not accepted	HostnamesVerified, with the reason	HostnamesVerified, by name. The reason is in that hostname's own status

The True message now reads "All hostnames have been accepted", and nothing outside the controller reads its text. The CRD and the API reference are regenerated from the corrected documentation.

Test plan

• The reconcile test checks the True message. It fails on the old text and passes on the new.
• The repository's generated-files check passes, and the linter reports no issues.
