ansible: quote file modes; keycloak: robust LDAP bind update + config cleanup

Highlights
- Quote all file modes as strings ("0755"/"0770") across multiple roles to avoid YAML octal quirks and improve portability.
- Keycloak: introduce actions.{import_realm,update_ldap_bind} feature flags and wire them via vars/config.
- Implement idempotent LDAP bind updater (tasks/03_update-ldap-bind.yml):
  * kcadm login with no_log protection,
  * fetch LDAP UserStorage component by name,
  * compare current bindDn/bindCredential and update only when changed.
- Keycloak realm import template: keep providerId="ldap" and set name from keycloak_ldap_component_name.
- Centralize Keycloak readiness check in tasks/main.yml; remove duplicate waits from 02_update_client_redirects.yml and 04_ssh_public_key.yml.
- 01_import.yml: fix typo (keycloak), quote modes, tidy spacing, and replace Jinja-in-Jinja fileglob with concatenation.
- 02_update_client_redirects.yml: correct assert fail_msg filename; keep login-first flow.
- Minor template/vars tidy-ups (spacing, comments, consistent variable usage).
