nextcloud(role): remove async → use batched shell; more robust changed_when/failed_when; fix quoting; refactor plugin routines; clean up vars

• 02_add_missing_indices.yml: switched to shell (+ansible_command_timeout), removed async/poll.

• 04_system_config.yml: batch OCC calls (set -euo pipefail, /bin/bash), safer quoting, change detection via ' set to '.

• 05_plugin.yml: disable task with stricter failed_when/changed_when (combine stdout+stderr).

• 06_plugin_routines.yml: disable incompatible plugins in a single batch; no async_status; robust changed_when.

• 07_plugin_enable_and_configure.yml: batch config:app:set, safe quoting, clear changed_when/failed_when.

• config/main.yml & vars/main.yml: removed performance.async.wait_for and nextcloud_wait_for_async_enabled.
