fix(ui): render partial target-bank states

Records 90 through 104 and 109 through 120 deactivate in linked three-line
groups. For each group, the flag-bearing head switches its recovered bounds
from overlay B to overlay A until the complete bank rearms every record. Rust
updated collision activity but never drew these nine intermediate states.

Render the five bumper-bank and four TDK-bank head regions directly from the
175-record ledger. Extend the bank regression to prove partial activation and
post-completion clearing, and seed two partial groups in the deterministic
rules framebuffer.

Test Plan:
- `cargo test --workspace --all-targets --all-features` -- 120 passed
- `cargo clippy --workspace --all-targets --all-features -- -D warnings` -- passed
- `rumdl check --flavor commonmark RECONSTRUCTION.md CHANGELOG.md` -- passed
- `cargo run -- --simulate targets --step 26 --screenshot /tmp/tdkpin-targets-banks.png` -- passed; partial bumper and TDK bank regions visually inspected at 640x460
- `git diff --cached --check` -- passed

 | Audio | Exact samples and recovered dispatch | All 16 mono PCM WAV resources are embedded unchanged. Playback is emitted at the reconstructed call sites, including multi-sound bank completions, nudge-then-tilt ordering, and Tilt suppression of the pre-reset WAVE-2008 drain cue. Like Win16 `SndPlaySound(SND_ASYNC|SND_NODEFAULT)`, each new resource stops the previous one and plays at the host mixer level without an application-side attenuation. WAV 2022 is loaded by the original generic resource loop but has no playback call and is therefore never played by Rust. |
 | Help and languages | Exact | Original resource images 1001-1005 are displayed directly. |
 | Playfield collision layout | Recovered | All 109 active type-2 line objects and 40 static active type-1 circles are transcribed from the original 175-object registration table. The registration routine converts its sideways inputs with `screen = (y, x - 20)` and accumulates explicitly relative objects. Every static record retains its `+0x49` layer mask; the scanner selects layer 1 below the old Y value 250,000 and layer 2 at or above it, while mask 3 records remain shared. Before detection, the raw `1000:9b69` predicted position must lie in the record bounds derived with the registered five-pixel ball margin. Type-2 records retain every recovered Real48 normal/tangent response pair and registered one-sided orientation. Type-1 records retain their swept-circle radius, radial rebound, tangent coupling, and bumper kick. Detection retains unresolved normal/material candidates so later scan-time motion changes can participate in the selected response. Raw stack slot `SS:...d8a2` makes the first detected record ID win; later nearer candidates are stored but never applied, and both C/Rust have two-candidate regression coverage for this quirk. Each flipper uses its exact two line records plus moving tip circle in both positions. Moving-flipper contact ports `1000:7ed9` rather than fitting live samples: delta-specific pivots/edges, integer cross gates, radial/penetration calculations, response-record gain, and position/velocity publication are tested against all four C harness directions and the raised release geometry. Object 174 is overwritten with the live first ball and Rust handles its ball-to-ball role directly. |
