Add more information to the contacts search results output

Is your feature request related to a problem? Please describe.

When searching the contacts using the search button located on the Nextcloud bar a user may see only name and email with the suggestion to see details. This is not enough for normal browsing.

Describe the solution you'd like

Please, add the possibility to customise the quick output results of the search for a contact by providing additional information in the search results, eg phone number(s), birthdate etc.

Describe alternatives you've considered

As almost all contacts have phone numbers comparing to emails I suggest at least to output phone number(s) in addition to names and emails.

Additional context

Contacts may have several emails and phones, it is good to add the primary one and output it or output all and indicate the type of phone/email, eg home/work.

Start with the contacts search opened from the Nextcloud bar and inspect how quick results currently present names and emails. Clarify which additional contact fields should be shown, whether primary or all values are required, and how customization should work; done means the requested information is visible in the search results.
