fix: propagate Cashu transaction storage failures

Comprehensive audit of all money-moving code paths on current main.
Found 8 live vulnerabilities where users, providers, or node runners
can lose funds, plus 1 false-green in the existing emergency refund
test suite.

Live vulnerabilities (all RED — tests assert correct/safe behaviour):

V-E1  send_refund() swallows DB failure after minting a refund token
      base.py ~line 3625 — except Exception: pass
V-E2  Emergency refund (chat) — same except: pass
      base.py ~line 3992 (existing test is a false green — 500-char
      window too short)
V-E3  Emergency refund (responses API) — identical pattern
      base.py ~line 4972
V-E4  Balance refund endpoint swallows DB failure
      balance.py ~line 628
V-E5  credit_balance() swallows 'in' transaction DB failure
      wallet.py ~line 1715
V-E6  EHBP refund token — except: pass after store
      ehbp.py ~line 762
V-E7  EHBP 'in' transaction — except: pass after store
      ehbp.py ~line 1028
V-E8  Admin withdraw returns token even when DB store fails
      admin.py ~line 475

V-E9  Window regression guard (GREEN) — documents the false-green in
      the existing test_emergency_refund_no_try_except_pass

Test results: 8 failed, 1 passed.

+"""RED tests for live money-loss vulnerabilities in routstr-core.
+
+Every test in this file asserts the CORRECT (safe) behaviour for a money
+path where a user, provider, or node runner can lose funds.  Each test
+FAILS against current ``main`` because the code is buggy — they are the
+"RED" phase of TDD.  Once the underlying bugs are fixed, they go green.
+
+== Vulnerability summary (all LIVE on main as of 2026-08-06) ==
+
+V-E1  send_refund() swallows DB failure after minting a refund token
+      base.py ~line 3625  —  except Exception: pass
+      Impact: refund token is minted at the Cashu mint but never recorded
+      in the DB.  The user receives the token in the X-Cashu header, but
+      if they lose it (or it never arrives) the refund endpoint cannot
+      look it up → permanently unrecoverable funds.
+
+V-E2  Emergency refund (chat) — same except: pass, false-green in the
+      existing test_emergency_refund_no_try_except_pass because the
+      500-char inspection window is too short to reach the except block.
+      base.py ~line 3992
+
+V-E3  Emergency refund (responses API) — identical pattern.
+      base.py ~line 4972
+
+V-E4  Balance refund endpoint swallows DB failure.
+      balance.py ~line 628  —  except Exception: pass
+
+V-E5  credit_balance() swallows "in" transaction DB failure.
+      wallet.py ~line 1715  —  except Exception: pass
+      Impact: token is redeemed and balance credited, but no "in" audit
+      row is stored.  The refund endpoint matches "in" → "out" by
+      request_id; a missing "in" row breaks that linkage.
+
+V-E6  EHBP refund token — except: pass after store.
+      ehbp.py ~line 762
+
+V-E7  EHBP "in" transaction — except: pass after store.
+      ehbp.py ~line 1028
+
+V-E8  Admin withdraw returns the token to the caller even when the DB
+      store fails.  The token is delivered but there is no audit trail.
+      admin.py ~line 475
+
+V-E9  Existing emergency-refund tests use a 500-char source window that
+      is too short to reach the except: pass block, producing a false
+      green.  This test verifies the window is wide enough.
