zeekayandHanzo Dev 23a1657d2e storage: original Hanzo storage layer, drop the relocated upstream ee code
features/storage/ was Papermark's ee/features/storage — commercial-licensed
code that commit 98f0da7fa renamed out of ee/ byte-identical rather than
deleting, leaving it under our AGPL root licence. Deleted and rewritten.

lib/storage/config.ts resolves one bucket from the environment. The upstream
version carried a hardcoded EU/US region matrix selected by the `usStorage`
feature flag; that flag is served by @vercel/edge-config, is false whenever
EDGE_CONFIG is unset, and no per-document region is persisted anywhere in the
schema — so the second region was unreachable on our deployments. Required
vars now throw at the boundary instead of resolving a partial config.

lib/storage/tus-store.ts builds a plain S3Store. MultiRegionS3Store subclassed
it and reassigned this.client/this.bucket per request on a shared instance, so
two concurrent uploads from different teams could observe each other's bucket.
Construction-time config removes the race. It also now forwards the endpoint,
so resumable uploads reach S3-compatible backends.

lib/files/aws-client.ts collapses to two functions: with one config the
team/non-team split was duplication, and getS3Client, getS3ClientForTeam and
getLambdaClient had no callers outside the module.

LICENSE: drop the carve-out clause pointing at ee/LICENSE and app/(ee) —
both directories are gone, so the pointer dangled. Papermark's copyright
line and the AGPL-3.0 text are untouched.
