fix(spaces): match owner DID format in space list + resolve all TS errors

Space dropdown showed "Request Access" for the owner's own space because
the /api/spaces endpoint only checked claims.sub against ownerDID, missing
the did🔑 format used by auto-provisioned spaces. Now uses dual-check
matching the resolveRole helper pattern.

Also fixes 15 pre-existing TypeScript errors:
- server/index.ts: add Hono AppEnv type for context variables
- modules/rnetwork/mod.ts: cast tuple index to number for arithmetic
- modules/rsplat/folk-splat-viewer.ts: type CDN-loaded three.js as any
- modules/rtube/mod.ts: cast Uint8Array to BlobPart for FormData
