scp81: continuation pages use GET STATUS P2=03 (next occurrence) (v2.1.15)

P2=02 means "get first or all occurrence(s)" (Table 11-34), so every
continuation re-returned the first listing (the criterion's single match),
pagination stopped after one extra page and the installed package
AA1902BC225801 never showed up in the ELF registry. P2=03 = "get next
occurrence(s)" is the correct value for the SW CAFE continuation.

Tests updated with the new continuation bytes; findings documented;

+## RESOLVED 2026-09-16f: SW CAFE pagination used the wrong P2 (02 instead of 03)
+
+**Root cause:** the continuation GET STATUS used `P2=02`, which Table 11-34
+(GP Card Spec 2.3.1) defines as "**Get first or all occurrence(s)**" - the
+card returned the first listing again (with the search criterion's single
+match), so every listing appeared to end after one extra page and newly
+installed/registered entries were invisible (the installed package
+`AA1902BC225801` was missing from the ELF registry). The correct value is
+`P2=03` = "**Get next occurrence(s)**".
+
+**Fix:** `_scp81_continuation` emits `80F2 <P1> 03 <Lc> 4F <len> <lastAID> 00`
+and the earlier duplicate entry per page is gone (the criterion entry is no
+longer re-returned).
