fix(Teams): Use string team IDs on teams iteration

[solracsf]

Summary

TeamManager::getSharedWithList() receives an array of team ID strings from TeamsApiController, but its fallback code path tries to call getId() on those strings as if they were Team objects.

server/core/Controller/TeamsApiController.php

Line 69 in 89fcefb

$sharesPerTeams = $this->teamManager->getSharedWithList(array_map(fn (Team $team): string => $team->getId(), $teams), $this->userId);

This PR changes the fallback to treat $teams as an array of IDs and matches the actual input contract from the controller to avoid the type error.
