doc(hooks): 📝 clarify post-gen print statements and README repository setup

• Replace nonexistent just configure-gitlab with actionable first-push guidance: push main immediately after remote creation, before any deliberate commits; note that bypasses are for the initial push only
• Correct --no-verify explanation: it skips local pre-push hooks, not branch protection; split those into separate remedies
• Add Owner-role-request as the first remedy for branch protection, with unprotect/reprotect as a fallback
• Add "Uncheck Initialize repository with a README" to README repo setup
• Prefix all auto-generated commits with chore(cookiecutter): 🍪 and a body line making clear they are not deliberate developer commits
• Split tag_branch CI rule into explicit when: never for main/develop plus a clean merge_request_event condition
• Move About block above Quick Start; fix broken wiki URL line wrap
