Merge pull request 'Release v1.14.0 — monetization launch (E5-E8)' (#237) from development into master

The Robokassa credentials reached only the test contour (ci.yaml → TEST_
secrets). The prod-deploy / prod-rollback workflows and write-prod-env.sh
never rendered BACKEND_ROBOKASSA_*, so on prod the shop login was empty and
the direct RUB rail stayed disabled — the PROD_BACKEND_ROBOKASSA_* secrets
went nowhere.

Export the shop login + Password1/Password2 (secrets) and a
BACKEND_ROBOKASSA_TEST flag (a variable, so go-live is a flag flip not a
secret rotation) from both prod workflows, and emit the four ROBOKASSA_*
vars from write-prod-env.sh (the shared deploy/rollback env renderer) so a
rollback keeps the rail up. The compose already maps ROBOKASSA_* →
BACKEND_ROBOKASSA_*. Document the new secrets/variable in the deploy README
and .env.example. Password3 (Robokassa's JWT-invoice API) is unused.

+- **`games.game_kind smallint DEFAULT 0`** (0=unknown — pre-E8 games, never gated; 1=vs_ai; 2=random;
+  3=friends), set on creation (`StartVsAI`=1, `Enqueue`=2, a friend invitation=3). Existing games
+  stay 0 and fall outside the gate.
+- **Limits are per-tier × per-kind**, in a **new single-row `backend.config`** table:
+  `guest_{vs_ai,random,friends}_limit` + `durable_{vs_ai,random,friends}_limit` (smallint,
+  **`-1`=unlimited**), seeded `(1,1,0, 10,10,10)`. A guest is capped at 1 vs_ai + 1 random (friends
+  is moot — the guest gate blocks friend games); a durable account is **10 per kind** — the old flat
+  MaxActiveQuickGames=10, now split per kind. Editable in the admin.
+- **The old flat cap is removed** (option A, owner-agreed): `MaxActiveQuickGames`,
+  `CountActiveQuickGames`, `atGameLimit` deleted; the per-tier/kind config is the single mechanism,
+  enforced at the **same handler gate** (`ensureUnderGameLimit(kind)` for `enqueue`
+  random/vs_ai) plus the durable **friends cap** inside `CreateInvitation`. The gate stays out of the
+  game domain — `game.Service.AtGameLimit(account, kind)` only resolves tier + counts.
+- **A hot in-memory cache** fronts the config (read once on start, invalidated on the admin edit —
+  mirrors the payments read-cache) so a login / game-create never queries it.
+- **"Active" = `open` + `active`** (an open, unmatched random game holds a slot); the limit is on
+  **creation** — an existing game is grandfathered, never interrupted.
+- **Limits ride the wire (forward-compat, no double break):** `Profile.game_limits`
+  (`GameLimits{vs_ai, random, friends}` — the caller's tier resolved server-side) + `GameView.kind`,
+  so the client counts active games **per kind** from its lobby and locks the right start button. On
+  a guest → durable upgrade (register / link) the client **re-fetches the profile** so the new
+  (durable) limits apply. The client picks the lock's message by tier: a **guest** → the login funnel;
+  a **durable** account at its cap → a plain "finish a current game first" notice.

+  and a **config editor** (`/_gm/limits`) for the six limits.
+- ~~**PR2 — wire + client** — DONE.~~ `Profile.game_limits` (the caller's tier) + `GameView.kind` (FBS
+  + gateway transcode + client codec, committed regen); the client counts active games per kind from
+  the lobby cache (`gamelimits.ts`) and locks a capped new-game start — an **outline 🔒** button that
+  opens `GameLimitModal` instead of a game, native (Telegram `showPopup`) or the in-app `Modal`
+  elsewhere, with two messages by tier: a **guest** sign-in funnel ("Войдите или создайте учётную
+  запись…", Отмена / Вход→`/settings`) and, for a **durable** account at its cap, a plain notice
+  ("Вы достигли лимита одновременных игр, сначала завершите текущие", ОК). The lock lifts via the
+  existing profile re-fetch after a guest→durable upgrade.
+  - **Decision (owner-agreed): the lobby's old `at_game_limit` New-Game tab-disable + notice is
+    removed.** The `at_game_limit` flag (now the random-kind cap) conflicted with the per-kind lock —
+    it hid the New-Game screen where the lock lives, and wrongly blocked starting an unfulfilled kind.
