Message Logger: show logged edits and deletions from telegram-panel [no bump]

Keeps deleted messages (75% opacity, red icon-pack trash icon), restores
logged messages deleted while away, reports deletions, and shows edit
history as a mock chat (Edit history in the message menu, Open topic).
Message links and history open as any signed-in account with access.
Per-master API tokens; chat state synced per checked range with an hour's
validity, cached in SQLite with a configurable lifetime.

+## Gotchas found on exteraGram 12.10.6 (message_logger)
+
+- **Java number boxing.** A Python `int` passed where Java takes `Object`, or to an overloaded
+  method, becomes a `Long` — even the result of `Integer.valueOf()`. Use `java.jint` /
+  `jfloat` explicitly: `ArrayList<Integer>` for `TL_*_getMessages.id` (a `Long` there fails
+  serialization on the network thread and the request silently never answers),
+  `Paint.setColor` (an `int` otherwise picks the `setColor(long)` ColorSpace overload),
+  reflective `Method.invoke` arguments, and replacing `param.args[i]` in hooks.
+- **Requests.** `client_utils.send_request` did not invoke the callback for these requests;
+  `ConnectionsManager.getInstance(account).sendRequest(req, RequestDelegate)` with a
+  `dynamic_proxy(RequestDelegate)` kept strongly referenced works (`src/tg.py`).
+- **Logs.** This device's logcat is silenced; `src/diag.py` mirrors to
+  `…/files/exteraGram/exteraGram Files/message_logger/diag.log` (readable over `adb shell cat`).
+- **Deploys.** `devclient.py deploy --enable` only enables; an already enabled plugin needs a
+  deploy without `--enable` (which reloads) to pick up a new build.
+- **Adding messages to an open chat.** Inserting into `ChatActivity.messages` directly (not in
+  `messagesDict`) breaks later arrivals in that chat; the private
+  `ChatActivity.processNewMessages(ArrayList, boolean)` places messages (also older ones) and
+  keeps the app's dicts and adapter consistent.
+- **Cell height.** Changing a `ChatMessageCell`'s measured height grows its bubble; after the
+  state behind it changes, `forceLayout()` the cell and `chatAdapter.notifyItemChanged(...)`,
+  or the list keeps stale positions. Item animators reset cell alpha: scale it in a
+  `setAlpha` before-hook instead of setting it once.
+- **Icon packs.** exteraGram applies icon packs through the activity's `ExteraResources`
+  (`getDrawableForDensity`); the application context's plain `Resources` and
+  `ColoredImageSpan(int)` give stock icons. Load drawables from
+  `get_last_fragment().getParentActivity().getResources()`.
+- **Another account's chat.** `BaseFragment.setCurrentAccount(slot)` before `presentFragment`
+  opens e.g. a `ChatActivity` as another signed-in account without switching accounts.
+- **Links.** Tapped links go through `org.telegram.messenger.browser.Browser.openUrl` (8 overloads,
+  the second argument a `Uri` or `String`); `adb shell am start -d URL` needs `-p <package>`.
+- **Message menu rows.** `MenuItemData` items land in the menu's Plugins folder, and options
+  added to `ChatActivity.fillMessageMenu`'s lists are dropped by exteraGram. A row in the main
+  menu is an `ActionBarMenuSubItem` inserted into the built popup after `createMenu` (whose
+  overloads call one another: insert once); `selectedObject` is the message.
+- **Topics as another account.** `ForumUtilities.openTopic` uses the presenting fragment's
+  account; do its steps yourself (`TopicsController.findTopic`/`loadTopic`, `ChatActivity`
+  with `setCurrentAccount` then `setThreadMessages`) — see `src/views/open_as.py`.
