Build allowance approval flow for delegating key transfers to staking contract

Summary

Implement the allowance approval UI that prompts users to approve the staking contract to transfer their keys before staking, using the on-chain approve mechanism.

Scope

Check existing allowance before staking flow begins
Approval step inserted in staking flow when allowance is insufficient
Approval transaction submitted and confirmed before stake proceeds
Approved state cached to avoid re-approval on subsequent stakes
Clear explanation of what the approval grants shown to user

Acceptance Criteria

Allowance checked before staking flow proceeds
Approval step shown only when allowance is insufficient
Approval transaction confirmed before stake submission
Cached approval bypasses approval step on subsequent stakes for same session
Explanation text clearly describes what the approval grants

Hi! I'd like to work on this.

Understanding:
Before staking, check if the staking contract has sufficient allowance to transfer the user's keys. If not, insert an approval step (on-chain approve call) into the staking flow, confirm it before proceeding, cache the approved state to skip re-prompting on later stakes, and clearly explain what the approval grants.

Planned approach:

Allowance check — On entering the staking flow, read current allowance for the connected wallet → staking contract (per key/asset) before rendering the stake action. Compare against the amount about to be staked.
Conditional approval step — Only inject the approval screen/step when allowance < requiredAmount. Skip entirely if sufficient.
Approval UI — A clear explanation panel: what's being approved (which contract, which key(s)/asset, and that it permits the staking contract to transfer on the user's behalf up to the approved amount), before the user signs.
Approval transaction — Submit approve, wait for confirmation (pending/success/error states), then automatically proceed to the stake transaction once confirmed — no separate manual re-trigger needed.
Caching — Store approved state (per wallet + contract + key, scoped to session or until allowance is later revoked) to bypass the approval step on subsequent stakes in the same session. Will use session storage or in-memory context depending on existing patterns — re-verify against actual on-chain allowance rather than trusting cache blindly, to avoid stale-approval bugs (e.g. if user revokes elsewhere).
Edge cases — Handle exact-allowance vs. unlimited-approval patterns (if the contract supports approving a fixed amount vs. max/infinite), and partial allowance (approved but insufficient for a larger stake —
