Support AGW Sessions batch revoking and detailed information

[rkalis]

Earlier this week there was an an app that got exploited on the Abstract chain by abusing "Sessions". These sessions are a way to allow third parties to call functions on behalf of the wallet.

• Support for inspecting and revoking AGW sessions
• Support for batch-revoking sessions
• Detailed information about permissions (not just how many different contract calls are authorised, but also which)

We have a first version of this implemented. The extensions listed in this issue can be picked up at some point, but it is quite a niche feature right now, so it's not the highest priority. Perhaps this is something that the Abstract team could contribute to, or offer a grant for.
