feat(system-builder): call a rest at the table (4f2b); fix CWN's LONG…

[over2take]

…_REST

GET /api/sheets/rests lists the running custom system's rests that are on (none for a built-in game). POST /api/sheets/rest calls or previews one: { rest, players: true | [names], npcs: [token ids], preview }. The GM and granted editors, as with the built-in rest buttons.

• sheets/rests.js: who rests (player characters in the running system, every one or the named ones whatever their case, each with its first token; chosen NPC tokens with the sheet linked to them in this game, or none). A preview rolls and writes nothing. Calling one works each sheet out inside its write queue, formulas worked out, so two rests at once both land and a player's edit is kept; then the token's health and conditions (a player's onto every token of theirs), one dice-log line each, and every screen told.
• resting.js: restLine and restDice, the log line and its dice.
• runtime.js: definitionOf.

Fix: CWN's LONG_REST had written SR6's Edge (edge = edge_max) onto CWN sheets since 821dae0 moved the resets onto the write queue, so it recovered no strain while reporting that it had. It takes 1 System Strain off every CWN sheet with some again, now with a test. The stray edge values it left behind are harmless and left as they are.
