Type Alias MigrateV1ToV2 

pub type MigrateV1ToV2<T, P, B, M> = VersionedMigration<1, 2, InnerMigrateV1ToV2<T, P, B, M>, Pallet<T>, <T as Config>::DbWeight>;

V1 to V2 migration: seeds BudgetAllocation, credits a one-shot catch-up drip for the window [P::get(), now], and initializes LastIssuanceTimestamp to now so regular drips start a fresh cadence from here.

• T: DAP pallet config
• P: Get<u64> providing the last inflation timestamp before DAP activation (e.g. ActiveEra.start from staking). Only used as an input to the catch-up drip — not persisted.
• B: Get<BudgetAllocationMap> providing the initial budget allocation.
• M: Get<u64> providing the maximum elapsed window (ms) the catch-up is allowed to credit. Should usually be max staking era length.

Idempotent: the catch-up is skipped if LastIssuanceTimestamp is already non-zero, so a re-entry does not double-credit.

The catch-up drip bypasses MaxElapsedPerDrip but is clamped by M as the one-shot safety ceiling.
