Overview

Users who regularly start new savings cycles with the same group (e.g. a monthly rotational pool that completes and the group wants to start a fresh one) currently have to manually re-enter every setting from scratch.

Requirements

• Add a "Start New Cycle" / "Duplicate Pool" button on completed pools in group-details.tsx
• Pre-fills the relevant creation form with the same pool type, deposit amount, round duration/target amount, and member list from the original pool
• User can edit any pre-filled value before submitting (it's a pre-fill, not a hard clone)
• Clearly indicate in the UI that this is a new, separate pool/contract, not a continuation of the old one

Acceptance Criteria

• Clicking "Duplicate Pool" navigates to the correct creation form with fields pre-populated
• All pre-filled values are editable
• Only available on pools the user actually created/administered (not any arbitrary pool)
• Creating the duplicated pool results in a genuinely new, independent contract deployment
