Report database size and make four genuine suites reproducible

Operations now report the SQLite database size and page count, read through
PRAGMA page_count/page_size in the same authority-checked batch as the
lifecycle counters with non-numeric values clamped to zero; the page renders
both and states that free disk space is still unknown.

replaceMoritaniAssassinationTraitors draws the first distinct physical Traitor
Card from the reserve instead of the reserve's first entry, because the face-up
set-aside card can still sit in that list: re-drawing it produced a receipt
whose replacement equalled the revealed card, which the assassination integrity
check rejects mid-Mentat. With no distinct card left the step is blocked with an
explicit reason instead of committing an invalid receipt.

Four tests were made reproducible after measuring their real failure rates,
because a suite that fails for random reasons cannot act as a checkpoint gate:
the Discovery typed Spice Blow test now removes other cards for the same
territory so one blow deposits the printed amount (0/20 after, ~20% before); the
Discovery E2 skills deal is pinned with the new shared
tests/deterministic-random.ts helper so a Lasgun-shield explosion cannot
pre-empt its skill consumer (0/12 after, ~20% before); the Ecaz Occupy Ix/CHOAM
policy check accepts any legal continuation and still asserts the phase it
reaches (0/30 after, ~10% before); and the mixed-E3 Moritani Cunning test keeps
the random storm off red_chasm's single sector (0/25 after, ~20% before).

Offline suite 7,801/7,801 with typecheck and lint clean. No game, seat, saved
state or deployment changes.
