feedback7 R22-LATE: an open detail card draws its field unit's current attack range — own board pieces in prep, any ally operator / summon in battle or on a scouted board; golden: unchanged

GitHub PR #281 by @IceCodeNew (this commit is substantially the PR, ported onto 0.2.2-dev; the field-detail range
idea after @BBleae's fork commits c6437f1 / b451bad, credited here instead of the PR's Co-authored-by trailers). The
unofficial skill-range preview the PR first had is gone (the owner's reply of 2026-10-07: only official-like
behaviour); what remains is the range the unit fights with now.

screens/game/range.js inspectRange resolves the open card's unit: an own board piece in prep (its loadout or
stand-in record, its facing — this replaces the prep selection's range effect); in battle or on a scouted board an
ally op / token on the field, at the snapshot's tile, with the live stats' range when there is one; never an enemy,
a dead or undeployed unit, or a scouted bench unit (UnitInfo `area` hand / temp — the tag the server sends since the
#385 fix; renderInfo now keeps it). shared/protocol.js unitStatsEntry gains an optional `dir` (the unit's facing now:
the snapshot tuples carry none and UnitInfo.dir is the facing at send time). tokenVariantFor moves to
gameLogic/loadout.js. Drag, the wheel and the pen clear the overlay.

Added on top of the PR: a test from the server's own scout m.field (board operator ranged, hand / temp none), docs
(PLAYING.md, design/client.md, design/network.md), comments.
Tests: test/ui/inspect-range.test.js (6), test/ui/playtest6_summons.test.js, test/match/unitStats.test.js;
test/ui/inspect-range.e2e.test.js (SP_E2E + CHROME_PATH: run here, 1/1). Golden unchanged (display; m.unitStats only).
