fix(data): resolve 170 more smartphone brand-prefix conflicts

Continues the brand-prefix dedup from #329/#330. Those resolved 414 pairs and
carried forward a residual of 353. This resolves 170 of that residual, source-
verified, and explicitly un-pairs 3 that are genuinely different devices.

Three sub-slices resolved (Refs #296):

1. 37 vendor/Wikipedia-sourced same-chip pairs. Same device, same physical chip
   (soc slugs differ only in spelling, e.g. `qualcomm-msm8974-snapdragon-800` vs
   `snapdragon-800`, `hisilicon-kirin-980` vs `kirin-980`), with battery/weight/ram
   already matching. Unlike the phonedb twins in #330, the twin here carries a
   Wikipedia or vendor page as its source, so its specific release_date is reliable
   and was adopted over the bare side's generic YYYY-01-01 placeholder (spot-checked:
   Huawei P30 Pro 2019-03-26 = GSMArena; LG G2 September 2013 = Wikipedia). Kept the
   canonical bare slug, unioned source_urls, set verified=true only where the twin
   was a vendor/Wikipedia source.

2. 7 same-model pairs whose two sides named different chips — verified against a
   cited source which side is correct, fixed the soc, then merged:
   - Oppo Find X8 Pro -> Dimensity 9400 (oppo.com launch; GSMArena)
   - Motorola Edge 50 Ultra -> Snapdragon 8s Gen 3 (motorola.com; phonearena)
   - Honor Magic V3 -> Snapdragon 8 Gen 3 (phonearena SM8650-AB; honor.com)
   - OnePlus Nord CE 2 Lite (Snapdragon 695), Nord CE 2 (Dimensity 900),
     Sony Xperia Z (APQ8064 S4 Pro), Honor Magic V2 (Snapdragon 8 Gen 2) —
     the bare side already held the correct chip; merged and cited GSMArena/vendor.

3. 126 pairs where the soc slugs are the same physical chip via a spelling variant,
   or one side's soc was a vague descriptor (`dual-core 1.0 GHz`, `<brand> mobile
   platform`, `n-a`) and the twin named the specific FK-valid part. Kept the
   GSMArena (bare) record, adopted the specific soc when the keeper's was vague,
   rejected the phonedb stamped placeholders (weight 150.0 / battery 1500), left the
   (unreliable) phonedb dates alone, unioned source_urls, deleted the twin.

Un-paired as genuinely different devices (left as separate records, no merge):
- HTC: `one-m9` holds the One M9+ (Helio X10) vs the One M9 (Snapdragon 810).
- Motorola: `razr` holds the 2023 Razr (SD 8+ Gen 1) vs the 2019 Razr (SD 710).
- Sony: `xperia-z3` holds the Xperia Z3+ (SD 810) vs the Xperia Z3 (SD 801).

No value invented; every repaired field cites its evidence URL in source_urls.
Left unresolved for a later pass (documented on #296): 21 same-model pairs whose
correct chip I could not source this round (includes the Huawei P50 Pro, which
genuinely shipped both Kirin 9000 and Snapdragon 888 SKUs), 157 pairs needing a
per-record ram/weight/battery source, and 2 odd/other pairs.

Both gates pass: `python -m app.validate` and `integrity_check.py <data> --strict`
(0 hard anomalies).
