feat: navigate from Marktsignale tab to Anfragencenter latente Anfragen

'Angebot erstellen' button in Marktsignale tab pre-selects the property
in the offer store and navigates to /supply/anfragen on the Latente
Anfragen tab. Also fixes offerWizardStore.open() to preserve
selectedPropertyIds so pre-selection survives the wizard open call.
