PR Summary

Medium Risk
Changes tenant-switch storage behavior in worker processes; incorrect flushing could misroute reads/writes across tenant and landlord storage.

Overview
Fixes tenant isolation for file I/O in long-lived Horizon/Octane workers where Laravel’s FilesystemManager kept cached disk adapters pointed at the previous root even after multitenancy config was rewritten.

SwitchTenant now calls a new flushFilesystemDisks helper after tenant disk roots (and lang disk) are updated in makeCurrent, and again when forgetCurrent restores landlord filesystems.disks roots/URLs before other teardown. Flushing uses Storage::forgetDisk and drops the filesystem container binding so the next Storage::disk() resolves the correct tenant or landlord path.

A unit test warms the landlord local disk, switches to a fake tenant, asserts paths under storage/tenant_{id}, and verifies forgetCurrent restores the original landlord path.
