- Fix `matrxi_appservice_draupnir_for_all_zero_touch_deployment` typo in
  the appservice doc example so the variable actually matches the role
  default (`matrix_appservice_draupnir_for_all_zero_touch_deploy`).
- Drop a garbled sentence in the appservice usage section.
- Restructure the bot-mode "Adjusting the playbook configuration"
  section into clearly labeled ZTD vs. native-login subsections so the
  access-token vs. native-login choice is unambiguous.
- Restore an example block under the (now uncommented) `pollReports`
  paragraph in the bot-mode doc.
- Reorder the orphaned "automatically done if Ketesa is enabled"
  sentence so it precedes the code block it qualifies.
- Fix `SPDX-FileCopyRightText` casing and normalize `2024,2026` /
  `2024, 2026` to the project's `YYYY - YYYY` convention.
- Fix variable name references in role default comments
  (`matrix_*_initialManager` -> `matrix_*_config_initialManager`).
- Misc grammar/spelling fixes ("the the", "a admin", "mittigated",
  "recommendationare", "News memory", "re creation", "an Synapse").
- Drop a stray double blank line in the appservice template.
