feedback7 R22-LATE: a watched teammate's bond popup counts their bench like their own popup — hand operators owned (and counted for 投资人 / 远见 / 奇迹), temp ones never, neither 在场; golden: unchanged

GitHub #385 / PR #387 by @zasx77771. The prep scout sends the hand and the 临时整备区 as units, and ownerBoard put every
op unit on the popup's synthetic board, so the popup marked bench operators 在场 and its 成员 header disagreed with the
server's ring (炎: ring 1, header 3; 远见: ring 2, header 3 with the temp copy).

The scout's units now carry `area` 'board' | 'hand' | 'temp' (the server tags from PR #387; the tag survives the
boss-half remap, the row does not). ownerBoard sorts them into board / hand / temp instead of dropping the bench as
the PR did: dropping the hand would break the bonds that count the 整备区 (投资人 / 远见 / 奇迹 — a hand-only 远见
member: ring 1, header 0). bondMembers / memberHeadCount then count exactly as the player's own popup: hand = owned
and in hand, temp = owned only. A unit without an area (battles, older servers) stays on the board.

Docs: PLAYING.md's 观看谁 paragraph (the bench is listed in prep); comments in bondStrip.js / game.js.
Tests: test/ui/watch-bonds.test.js (36; 2 fail on the parent), test/match/prep-bench.test.js +
feedback5-boss-pair-prep.test.js (area tags; 4 fail on the parent). Golden unchanged (views only).
