fix: set username grace period and deposit (#416)

Browse source 
### Summary
Set username deletion to use a 30‑day grace period (in blocks) and added
a non‑zero username deposit, both based on the Moonbeam's runtimes. This
makes username unbinding wait before deletion and makes authority‑issued
usernames non‑free, mitigating the sybil vector while aligning with
existing identity config patterns.

### Changes
- Configures for `pallet_identity`
  - `UsernameGracePeriod = 30 * DAYS`
  - `UsernameGracePeriod = deposit(0, MaxUsernameLength::get())`
