[FEATURE] search for an email address simultaneously in to, cc and bcc

[defrance]

Description

Add two additional options for contact searches:

• all recipients (search performed on the to, cc, bcc fields with an OR condition)
• all senders and recipients (add the from field to the previous search)

At the API level, add two additional corresponding filters: toccbcc and fromtoccbcc

Purpose / Use Case

When searching for an email you sent to someone but don't know if the recipient was in "to", "cc" or "bcc", if you put the same email address in each filter, an "AND" operation occurs, whereas the most relevant solution would be an "OR" or a search across all recipients.

Additional Information (optional)

Any extra ideas or context.
