refactor!: simplify query and session ownership

Use Query cancellation and native mutation results instead of HTTP
registries, access epochs and copied scope state.
Keep local auth ordering and mutation identity fences.
Allow staged generated files to remain excluded from ESLint.

Backend contract: WealthLedger/backend@d698ed9

BREAKING CHANGE: drop investment stateVersion/progress/resources
from the client contract and use data/metadata readiness instead of
rewritten query status. Cross-tab auth may require re-login.
