chore: migrate to wagmi v3

[wenfix]

Explanation

Upgrades wagmi and related dependencies to their latest versions, and applies the required v2→v3 migration changes.

Package bumps

Package	Before	After
wagmi	^2.19.2	^3.5.0
@wagmi/core	^2.22.1	^3.4.0
@wagmi/cli	^2.3.2	^2.10.0
@tanstack/react-query	>=5.45.1	^5.90.21
@tanstack/react-query-persist-client	5.0.5	^5.90.24
@tanstack/react-query-devtools	5.0.5	^5.91.3
@tanstack/query-sync-storage-persister	5.0.5	^5.90.24
@tanstack/query-async-storage-persister	5.0.5	^5.90.24

viem remains at 2.* — wagmi 3.x still targets viem 2.x.

wagmi v3 migration changes

wagmi v3 renamed several hooks and removed properties that were accessible via destructuring:

• useConnect().connectors removed → use useConnectors() standalone hook
• useSwitchChain().chains removed → use useChains() standalone hook
• useSwitchAccount().connectors removed → derive from useConnections().map(c => c.connector)
• useAccount → useConnection
• useAccountEffect → useConnectionEffect
• useSwitchAccount → useSwitchConnection
