Team-mailbox - folder management

[chibenwa]

Context

Backend added in a serie of tickets good support for managing team mailboxes folders:

• Team mailbox: ability to remove custom folders tmail-backend#1530 remove team mailbox folder
• Team mailboxes: ability to rename custom folders tmail-backend#1552 rename / move custom folders
• Team mailbox: ability to create folders tmail-backend#1505 create team mailbox folders

We need to add support for this in fromtend too

Definition of done

Base frontend folder management action on the 'right' properties of the folders: https://jmap.io/spec-mail.html#mailboxes

myRights: MailboxRights (server-set) The set of rights (Access Control Lists (ACLs)) the user has in relation to this Mailbox. These are backwards compatible with IMAP ACLs, as defined in [@!RFC4314]. A MailboxRights object has the following properties:

    mayReadItems: Boolean If true, the user may use this Mailbox as part of a filter in an Email/query call, and the Mailbox may be included in the mailboxIds property of Email objects. Email objects may be fetched if they are in at least one Mailbox with this permission. If a sub-Mailbox is shared but not the parent Mailbox, this may be false. Corresponds to IMAP ACLs lr (if mapping from IMAP, both are required for this to be true).
    mayAddItems: Boolean The user may add mail to this Mailbox (by either creating a new Email or moving an existing one). Corresponds to IMAP ACL i.
    mayRemoveItems: Boolean The user may remove mail from this Mailbox (by either changing the Mailboxes of an Email or destroying the Email). Corresponds to IMAP ACLs te (if mapping from IMAP, both are required for this to be true).
    maySetSeen: Boolean The user may add or remove the $seen keyword to/from an Email. If an Email belongs to multiple Mailboxes, the user may only modify $seen if they have this permission for all of the Mailboxes. Corresponds to IMAP ACL s.
    maySetKeywords: Boolean The user may add or remove any keyword other than $seen to/from an Email. If an Email belongs to multiple Mailboxes, the user may only modify keywords if they have this permission for all of the Mailboxes. Corresponds to IMAP ACL w.
    mayCreateChild: Boolean The user may create a Mailbox with this Mailbox as its parent. Corresponds to IMAP ACL k.
    mayRename: Boolean The user may rename the Mailbox or make it a child of another Mailbox. Corresponds to IMAP ACL x (although this covers both rename and delete permissions).
    mayDelete: Boolean The user may delete the Mailbox itself. Corresponds to IMAP ACL x (although this covers both rename and delete permissions).
    maySubmit: Boolean Messages may be submitted directly to this Mailbox. Corresponds to IMAP ACL p.
