chore(v2): dead-code purge (fix bundle 3)

~1300 lines removed across four cleanups. Pure deletions; no behavioural
changes.

1. **transaction_processor.py — DELETED (1274 lines).** Orphaned v1 file
   that hasn't been imported anywhere since fix-bundle-1 wired the v2
   distribution chain. The historical Lamassu logic is preserved in git
   history at any commit on main.

2. **views_api.v2_in_progress_stub — DELETED.** The catch-all that
   returned 503 for any unmatched /api/v1/dca/* path. With P3a–P9g
   shipped, every documented endpoint is implemented; the catch-all was
   stale and (per issue #11 M7) unauthenticated, so it leaked the
   extension's existence to anonymous probes. Removed entirely.

3. **tasks.hourly_transaction_polling — DELETED.** v1 LegacyLamassu
   polling no-op. The associated `create_permanent_unique_task` spawn
   in __init__.py is also gone (was spawning a forever-sleeping task
   for no reason).

4. **__init__.py scaffolding artifacts.**
   - Replaced the placeholder "you can debug in your extension using
     'import logger from loguru'" template log with a meaningful
     "satmachineadmin v2 loaded" INFO line.
   - Dropped the now-stale `hourly_transaction_polling` import + spawn.
   - Sorted __all__ (RUF022).

Migration collapse (m001..m007 → single m001_v2_initial) was on the
fix-bundle-3 list but is deferred to a separate PR. The current
migrations are harmless on fresh installs (idempotent CREATE/DROP
chain) and collapsing them risks breaking the LNbits version tracker
on the off chance any operator has v1 data; better to do that as a
dedicated migration-discipline change once we're confident no v1
operator data exists in the wild.

Routes: 34 → 33 (catch-all gone). 76/76 tests pass.

Refs: aiolabs/satmachineadmin#11 — fix bundle 3 ✅ (modulo migration
collapse). Remaining in #11: M1-M12 + N1-N12.
