[PM-18046] Implement session storage (#17346)

* feat: add support for IPC client managed session storage

* feat: update SDK

* fix: using undecorated service in jslib module directly

* feat: add test case for web

* chore: document why we use any type

* fix: `ipc` too short

* typo: omg

* Revert "typo: omg"

This reverts commit 559b05eb5a.

* Revert "fix: `ipc` too short"

This reverts commit 35fc99e10b.
