Display total of signatures in delegate vault panel

[edouardparis]

delegate vault panel should display the list of secured and activating vaults with the number or signatures attached for delegation.

Further, it should sort first by the number of signatures and second by deposit outpoint (lexicographic order). The former completes the synchronization of the delegation introduced by having the number of signatures, and the latter allows for a deterministic ordering of the vaults list. Then we'll be able to give them smaller ids (#1, #2, #3, #4, ...).

[edouardparis]

We agreed now for a list of all the secured and activating vaults with a use choosen filter with the approved or unapproved values and the following order:

• first the number of signatures in the unvault transactions, higher first
• second the amount, higher first
