Follow-up from "Search improvements"

The following problems were found in Beta-testing:

• It should not be possible to search for single letter words only (like "e e e") because it causes severe search times
• Buddy status is not displayed
• Some mail addresses get displayed as xyz@foodsharing.network@foodsharing.network
• Allow searching for last names using at least 3 chars
• Some search queries result in server errors
• Display if users are verified
• Sort chats by Number of members
• Re-implement client side search for buddies and objects the user is member for
• Allow searching for word starts, maybe like ^Anne or "Anne" (not matching Susanne)
• Allow opening the search with Shift+F
• Make result lists expandable and show only a few in collapsed state
• Remove query words that are substrings of others
• Info if there are no results
• Improve store search speed
• Allow Orga users to search non-globally (global search as Opt-in)
• Allow navigating results using tab effectively
• Display info on too short search terms
• Use php attributes for Rest API
• declare strict types
• Create general vue component for entry type lists
• Allow admins of AG Support to search globally like Orga
• Don't include the @foodsharing.network in the search
• Use mailbox table for region emails
• Don't link Home region
• Allow directly copying foodsaver id
• Select query upon reopening search window
• Automatically refresh search when changing between global and normal search
• Allow searching for Mails
• Allow searching for Events
• Allow searching for Polls
• Handle priority in forum threads correctly
• Parallelize db queries (based on the timing results, this seems to be quite useless)
• Fix accidental clicks after loading new entries
