data(smartphone,tablet): extract dimensions + wired charging from raw spec (3,118)

[Seungpyo1007]

Summary

Extracts two more structured fields from the full GSMArena spec blob (raw_phones_2024) already stored on each record — deterministic parse, no new/external data.

• dimensions (+3,101) — Body.Dimensions "147 x 72.5 x 7.1 mm …" → {height_mm, width_mm, depth_mm} (matches the existing field shape).
• charging_wired_w (+1,614) — Battery.Charging "18W wired, QC2" → 18.0 (wireless/IP data absent for these mostly-older records, so those fields are untouched).

Applies to smartphone + tablet; 3,118 records touched. All verified: false. Validation passes. Dump regenerated — 3,118 changed detail pages.

Closes #1

• Parsed from raw_phones_2024.Body.Dimensions and .Battery.Charging; dimension order H×W×D verified against the existing {height_mm,width_mm,depth_mm} shape.
• Dump regenerated: 3,118 smartphone + tablet detail pages.

🤖 TechEngine · verify (Tier 0)

Structured extraction from the record's own stored spec blob, not an import:

• dimensions parsed with a bounds guard (0 < h,w < 400 mm, 0 < depth < 80 mm); the "in" values in the source are ignored — only the mm triple is taken.
• charging_wired_w takes the wired wattage, explicitly removing any "N W wireless" token first so the two never cross-contaminate; guarded to [2, 500] W.
• Records already carrying either field are left untouched.

verified unchanged (false). Safe to rebase-merge.
