docs: point all ladder entrypoints at modular amount ladder

Drop remaining check_goa_ladder / old-shim wording. Document ladder/
modules, goa-ladder as phase alias only, and max-ladder as wd+pay
max-search. Update admin-log goa-withdraw-ladder comments to prefer
taler-monitoring.sh ladder|max-ladder.

 #
-# Currency-agnostic bank landing ladder for GOA, TESTPAYSAN, KUDOS, …
-# (formerly check_goa_ladder.sh; use phase ladder / max-ladder / goa-ladder).
+# Orchestrator for the modular amount ladder:
+#   Phase A withdraw — this file (classic plan or max-search)
+#   Phase B pay      — ladder/lib_pay.sh (classic list or max payable)
+#   Force-select     — ladder/extract_rpubs.py
+# See ladder/README.md.
 #
 # Flow (bank landings):
 #   1) GET /intro/auto-account.json  → personal *account-* (balance 0)
 #   2) Mint pool withdrawals as explorer + confirm when selected
 #   3) wallet-cli accept-uri only (no run-until-done)
 #   4) bank confirm when selected; settle = balance + transfer_done
+#   5) pay via free-amount template (GOA: goa-free) or private orders
 #
 # Modes (LADDER_MODE):
-#   classic  — random strictly increasing rungs + pins 0, max-1, max (default 23)
+#   classic  — default 23-rung withdraw + matching pay plan (pins 0, max-1, max)
 #   max      — max-search: highest withdrawable AND highest payable
 #              (pay never exceeds wallet available; GOA uses public free-amount
 #              template goa-free by default)

 ## Modes
 
-- **classic** (default): withdraw plan 0→mids→max-1→max, then matching pay plan (never overspend).
+- **classic** (default): 23-rung withdraw 0→mids→max-1→max, then matching pay plan (never overspend).
 - **max** (`max-ladder`): adaptive max withdraw, then adaptive max pay via public free template (hacktivism: `goa-free`).
