28-Apr-2026 — tidy unsubscribes view; share default content ref #18

build 628 — commit 1e9f009

Brevo Unsubscribes admin page polish:

• Show contact email/name in full in the Name column (was truncated to "..." behind a hover tooltip).
• Drop the Stats column; widen Search/Reason/Sender to fill the freed width.
• Move the Unsubscribes/Blocks toggle inside the frame (was crossing the frame border with a white legend cover).
• Reduce vertical gap between heading and filter labels by reordering the help-editor row to sit below the filter row.
• Help text trimmed to a four-bullet summary pointing at the release notes for full detail.

Default-content single-source-of-truth:

• Extract the inline defaultContentArray() from data-population.service.ts into a non-Angular sibling module default-content.ts so both the runtime fallback and database migrations can import the same entries.
• New shared upsert-content-text.ts helper for content-text seed migrations.
• New migration 20260427210000-refresh-mail-settings-unsubscribes-help refreshes the help text on environments where the earlier 0425 seed migration has already run with the older content (Salesforce column reference removed).
