fix(rewards): stop the stuck "No higher tier has been confirmed" notice

[MusabShakeel576]

Problem

At the top of Explore Tiers, users see "Savings refreshed. No higher tier has been confirmed yet. Check your FUSE Savings balance and tier requirement before adding more." It shows up for people who are already on the tier they're looking at, including Ultra, which has nothing above it. It stays there until the app restarts.

It comes from a 90-second "wait for a promotion" window in useRewardsUpgradeStore. If the window ran out without a higher tier, timedOut was set and the screen showed the notice. These actions all opened the window, and none of them can raise a tier any more:

• yield-boost claims (useClaimYieldBoost)
• FUSE savings deposits (useDepositFromSolidFuse)
• realtime balance events
• cancelling or resuming a membership
• a lock that keeps a trial tier (the "Keep Ultra" button), where the tier never goes up

How many users this hit (Oct 1–8)

Trigger	Users	Count
Yield-boost claims (yieldBoostClaims, all paid)	84	191 claims
… of which on an active Ultra trial	13	32
… of which on an active Prime trial	37	62
Tier locks (Amplitude Tier Lock Completed, last 30d)	19	16 Prime / 3 Ultra
Annual-fee subscriptions	4	—

A yield-boost claim almost always ended on the notice, so about 84 users have likely seen it since the boost launched on Oct 1. Our data can't tell which of the 19 lockers already held their tier through the old soFUSE rule, so we don't know how many of them saw it. I found no existing monday.com item for this bug.

Fix

Only a lock or an annual fee raises a tier now, so:

• savingsChanged → tierPurchased. Only useLockFuseForTier and useSubscribeToTier start the window. Cancel and resume now just refresh data.
• refreshRewardsAfterSavings still refetches rewards and balances, but no longer starts the window. The confirmedSavings flag is gone.
• The window now ends silently. The lock or subscription is already confirmed on-chain when the window opens, so running out only means the new tier is slow to appear. The notice and the timedOut / savingsConfirmed state are removed.
• The pending selectors on the benefits and Buy FUSE screens are now just !!pendingUntil.

The celebration after a real upgrade, and the 90-second polling that catches it, work the same as before.

Testing

• jest on the reward-store, rewards-hook, deposit, realtime, swap and Buy FUSE suites, plus a new refreshRewardsAfterSavings test: 8 suites, 82 tests pass.
• eslint and prettier --check pass on the changed files.
• tsc --noEmit reports no errors in the changed files. The 8 errors it does report are in files this PR doesn't touch and are already on master.
