Type Alias OffenceQueueEras 

pub type OffenceQueueEras<T: Config> = StorageValue<_GeneratedPrefixForStorageOffenceQueueEras<T>, WeakBoundedVec<u32, T::BondingDuration>>;

Tracks the eras that contain offences in OffenceQueue, sorted from earliest to latest.

• This ensures efficient retrieval of the oldest offence without iterating through OffenceQueue.
• When a new offence is added to OffenceQueue, its era is inserted in sorted order if not already present.
• When all offences for an era are processed, it is removed from this list.
• The maximum length of this vector is bounded by BondingDuration.

This eliminates the need for expensive iteration and sorting when fetching the next offence to process.

Storage type is StorageValue with value type WeakBoundedVec < u32, T :: BondingDuration >.
