schalli d12e1c9aa9 feat(11-02): implement NUTS-1 to Bundesland derivation
bundeslandFromRegion() derives one of the 16 Bundesland names from a
region's NUTS-1 (3-char) prefix; nutsPrefixFor() reverses a Bundesland
name back to its prefix for the query builder. Null-safe throughout —
7/7 tests green, validated against real region samples from the live DB.
