feat(cms): clarify sponsor ordering

+## Partner collection administration
+
+The Partners list defaults to `name`, `tier`, `sortOrder`, `_status`, `active`, `showOnHomepage`, and `updatedAt`, so editors can review presentation order and visibility without opening every record. `tier` accepts only the numeric values 1, 2, and 3. Within each tier, lower `sortOrder` values render first; tiers remain separate presentation bands.
+
+The current published local CMS data was verified on 2026-07-31 in this client-review order:
+
+| Review order | Partner | Tier | `sortOrder` |
+| ---: | --- | ---: | ---: |
+| 1 | RSM Ebner Stolz | 1 | 1 |
+| 2 | WWK | 1 | 2 |
+| 3 | Radio Gong 96.3 | 2 | 3 |
+| 4 | münchen.tv | 2 | 4 |
+| 5 | METZLER | 3 | 5 |
+| 6 | Dr. Wieselhuber & Partner | 3 | 6 |
+| 7 | Fristads | 3 | 7 |
+| 8 | New Edge | 3 | 8 |
+| 9 | Moodtalk | 3 | 9 |
+| 10 | Deutsche Bank | 3 | 10 |
+| 11 | Bionorica | 3 | 11 |
+| 12 | Primus | 3 | 12 |
+
+Future sponsor order changes are CMS content operations: edit the relevant Partner records' `tier` and `sortOrder` values. They do not require frontend code changes.
