feat: l for details; details for vaults, scopes and files; getting started; the age of cached lists (#17)

- `l` goes to the details of what is selected; `enter` still drills in
- vaults, scopes and files show their details (vault settings from the listing, no extra requests)
- with nothing to show, the right pane says how to get started
- a list from the cache says how old it is while it reloads
- what is expiring, in the status pane and `lazysecrets expiring`
- when access is refused, what to check, for Azure and Databricks
- no group list in an account's details, and no Microsoft Graph call for it
