Add SQLite, account creation, and account fetching

[dguenther]

Changes

• Adds SQLite using Kysely
• Adds a DatabaseLoader component to _layout.tsx that runs an initialization migration (like in the node app)
• Updates data-facade to pass through mutation options to allow clearing the query cache after a mutation
• Adds account handlers that use SQLite. The old handlers with test data are now in the same folder called demoHandlers (I'm down to restructure these to something different)

Fixes IFL-2422

suggestion: IIRC, it's possible to set a default for this with React Query. I'd recommend busting the whole cache on mutation. IMO, being overly aggressive with cache busting after a mutation is usually the way to go; especially for stuff like accounts that will be on-device, so the request doesn't even need to go over the wire.

I think in the node app, we handle this at the trpc-react level: https://github.com/iron-fish/ironfish-node-app/blob/9712ebf2cd64507b42b8a055ab9efebc9a808f6d/renderer/providers/TRPCProvider.tsx#L14

So I think we'd need to add something to data-facade to allow for this? We can pass defaultOptions to the QueryClient to set onSuccess by default, but it would get clobbered if we wanted to set onSuccess on mutations explicitly.

I'm going to kick this down the road and add a ticket in Linear for it: https://linear.app/if-labs/issue/IFL-2522/invalidate-react-query-query-cache-on-all-mutations
