chore(deps): update dependency charset-normalizer to v3.4.7

Avoid reopening a transition window where Synapse can accept new registrations or other auth changes
after syn2mas completes but before the MAS cutover is finalized.

Inspired by and continuing the work done in: https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/5097

+## Migration validation system introduced
+
+Previously, when updating your setup, you had to remember to read the [CHANGELOG](CHANGELOG.md) file or risk breakage.
+
+Now, the playbook includes a migration validation system that ensures you're aware of breaking changes before they affect your deployment.
+You're now forced to acknowledge each breaking change, unless you wish to live dangerously (see below).
+
+A new `matrix_playbook_migration_validated_version` variable has been introduced.
+
+**New users** who started from the [example `vars.yml`](examples/vars.yml) file already have this variable set and do not need to do anything.
+
+**Existing users** will need to add the following to their `vars.yml` file after reviewing all changelog entries up to now:
+
+```yml
+matrix_playbook_migration_validated_version: v2026.03.23.0
+```
+
+Going forward, whenever a breaking change is introduced the playbook will:
+
+- bump its expected version value (`matrix_playbook_migration_expected_version`), causing a discrepancy with what you validated (`matrix_playbook_migration_validated_version`)
+
+- fail when you run it with a helpful message listing what changed and linking to the relevant changelog entries
+
+After reviewing and adapting your setup, you simply update the variable to the new version.
+
+If you'd like to live dangerously and skip these checks (not recommended), you can set this once and be done with it:
+
+```yml
+matrix_playbook_migration_validated_version: "{{ matrix_playbook_migration_expected_version }}"
+```

+- name: Fail if migration version is not validated (first-time onboarding)

+    msg: >-
+      This playbook now uses a migration validation system to help you stay aware of breaking changes.
+
+      It appears that you haven't configured the `matrix_playbook_migration_validated_version` variable yet.
+
+      Please review the changelog (https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/CHANGELOG.md)
+      and then add the following to your vars.yml file:
+
+      matrix_playbook_migration_validated_version: {{ matrix_playbook_migration_expected_version }}
+  when: "matrix_playbook_migration_validated_version == ''"
+
+- name: Fail if migration version is outdated
+  ansible.builtin.fail:
+    msg: |-
+      Your validated migration version ({{ matrix_playbook_migration_validated_version }}) is behind the expected version ({{ matrix_playbook_migration_expected_version }}).
+
+      The following breaking changes have been introduced since your last validation:
+
+      {% for item in matrix_playbook_migration_breaking_changes | selectattr('version', '>', matrix_playbook_migration_validated_version) | sort(attribute='version') %}
+      - {{ item.version }}: {{ item.summary }} ({{ item.changelog_url }})
+      {% endfor %}
+
+      After reviewing the above changes and adapting your setup, update your vars.yml:
+
+      matrix_playbook_migration_validated_version: "{{ matrix_playbook_migration_expected_version }}"
+  when: "matrix_playbook_migration_validated_version != '' and matrix_playbook_migration_validated_version < matrix_playbook_migration_expected_version"
