[ThomasAFink]

Summary

• Unbolds service (Leistung) links in confirmation, reminder, and activation mails
• Normalizes separators to a single Geviertstrich (—) instead of ——
• Reduces excess spacing under “Termin aktivieren”, under the location block, under preparation bullet lists, and around separators
• Stacked on feat(ZMSKVR-1557): add estimated duration to confirmation and reminder mails #2992 (ZMSKVR-1557); retarget to next after that merges

📝 Walkthrough

Walkthrough

The PR adds four transactional migrations that normalize mail template separators, spacing, and service-link markup. It also updates shared templates to use em-dash separators and removes selected custom mail templates.

Changes

Mail template normalization

Layer / File(s)	Summary
Transaction scope and service-link cleanup zmsbackend/migrations/91785035201-format-mail-templates-spacing-and-dashes.sql, zmsbackend/migrations/91785035202-format-mail-templates-ascii-hyphen-separators.sql	The migrations run guarded updates within transactions. Service-link <strong> wrappers are removed while links and request-group names remain.
Separator normalization zmsbackend/migrations/91785035201-format-mail-templates-spacing-and-dashes.sql, zmsbackend/migrations/91785035202-format-mail-templates-ascii-hyphen-separators.sql, zmsbackend/migrations/91785035203-format-mail-templates-double-emdash-separator.sql, zmsbackend/migrations/91785035204-format-mail-templates-remaining-separators.sql	The migrations convert ASCII, em-dash, and en-dash separator variants to canonical non-wrapping em-dash blocks.
Spacing normalization and final cleanup zmsbackend/migrations/91785035201-format-mail-templates-spacing-and-dashes.sql, zmsbackend/migrations/91785035202-format-mail-templates-ascii-hyphen-separators.sql	Break spacing around separators and below the “Termin aktivieren” link is reduced. Remaining duplicate em dashes are replaced.
Template separator updates and custom-template removal zmsentities/templates/messaging/mail_confirmation.twig, zmsentities/templates/messaging/mail_queued.twig, zmsentities/templates/messaging/mail_reminder.twig, zmsentities/templates/messaging/custom/*	Shared templates use non-wrapping em-dash separators. Selected Füh­rer­scheinstelle and KFZ-Zulassungsstelle custom templates are deleted.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to d3041

The current head can leave some emails with doubled separators or unchanged spacing variants, causing inconsistent formatting for recipients. The impact is limited to email presentation, so the PR is mergeable with explicit owner follow-up to correct the replacements and guards.
