ddidderr 0c52100a7e fix(game): restore per-player secondary scoring
Replace the global bonus approximation with the original per-player secondary
score and multiplier. Lock holes now accumulate 10k, 20k, 40k, 80k, and 160k;
the fifth transfer applies the current multiplier, clears the secondary score,
increments that multiplier, and grants the recovered extra-ball count.

Route effects 1 through 5 into the same secondary score and make effect 6
transfer its displayed multiplied value before clearing it. Render that value
on the table and stop adding an unrelated global bonus during drain, preserving
secondary progress across balls as the original player state does.

Test Plan:
- `cargo test --all-targets` -- passed, 57 tests
- `cargo clippy --all-targets -- -D warnings` -- passed
- `rumdl check tdkpin-rs/CHANGELOG.md tdkpin-rs/RECONSTRUCTION.md` -- passed
- `git diff --cached --check` -- passed

## [Unreleased]
### Fixed
- Store lock-hole and effect awards in the original per-player secondary score
instead of a global bonus. The fifth hole now transfers
`310000 * score_multiplier`, clears it, increments the multiplier and ball
count, while effect 6 transfers the same display value and drain leaves it
intact.
- Replace the cooldown/float-meter nudge approximation with the original
Left-Shift, keypad-3, and Space formulas using scalar 15, the shared Borland
random stream, 32-bit velocity wrapping, and the decaying 16-bit `+25` tilt
counter with its randomized `30..39` threshold.
- Replace the Xorshift gameplay RNG with the original Borland linear stream and
unbiased `Random(n)` high-word mapping. Launcher variation, effect selection,
claw terminals, and magnetic-field impulses now share the recovered sequence.
- Restore the magnetic-field response as `vx * 0.9` and a randomized
`-3800 * (1 - Random * 0.3)` vertical impulse instead of a fixed upward speed.
- Dispatch the original per-call-site sound sequences instead of assigning one
guessed WAV to each logical event. This removes the nonexistent WAV 2022
playback and restores bank, trigger, capture, nudge, tilt, and drain cues.
- Advance media/extra-ball thresholds only from score additions, preserve
32-bit score wrapping, and restore the ninth-diamond 24,464-point award plus
the later double-score and secondary-score bank states.
- Match the original 640x460 window, native 16x28 score glyphs, and
`TDK Pinball Machine 1.00` title so the recovered artwork is presented
one-for-one instead of enlarged or resampled.
