Feat: Alliance and betrayal hotkeys

[Jarifa]

Original Feature request by @FloPinguin #3077

Description:

Adds hotkeys for Requesting alliances and breaking alliances. This allows for players to send or break alliances whose tile is under the cursor, without opening the radial menu.

Keybinds:
New "Ally Keybinds" section in Settings -> Keybinds
Request alliance: Default: K - sends an alliance request to the player/bot/nation under the cursor
Break alliance: Default: L - breaks the alliance with the player at the cursor

Behavior:

• Cursor must be over a tile owned by the target player. The action runs only when the game allows it, following the same logic as the radial menu. (canSendAllianceRequest and canBreakAlliance)
• When an alliance request is sent, the events log shows: "Alliance request sent to [target]" for confirmation. No extra message for breaking an alliance (betrayal/debuff message already exists and is sent upon breaking an alliance)

Screenshots:

Keybind menu:

In game logs:

Please complete the following:

• I have added screenshots for all UI updates
• I process any text displayed to the user through translateText() and I've added it to the en.json file
• I have added relevant tests to the test directory
• I confirm I have thoroughly tested these changes and take full responsibility for any bugs introduced

Walkthrough

Adds alliance request and break-alliance actions: new keybinds, input events, client handlers that validate target ownership and permissions, intent events emitted, event display logging, and localization/UI entries for the new strings and keybinds.

Changes

Cohort / File(s)	Summary
Localization resources/lang/en.json	Added keys for ally keybinds and event text: ally_keybinds, request_alliance, request_alliance_desc, break_alliance, break_alliance_desc, alliance_request_sent.
Input events & keybind UI src/client/InputHandler.ts, src/client/UserSettingModal.ts	Introduced DoRequestAllianceEvent and DoBreakAllianceEvent; added keybinds (KeyK, KeyL) and corresponding UI blocks in user settings.
Client handlers src/client/ClientGameRunner.ts	Registered listeners for request/break events; added private handlers that resolve cursor tile, verify owner is a player, check permissions, and emit SendAllianceRequestIntentEvent or SendBreakAllianceIntentEvent.
Event display src/client/graphics/layers/EventsDisplay.ts	Subscribed to alliance intent events and appends an ALLIANCE_REQUEST event when current player sent a request, using recipient name and current game tick.

Poem

Two keys tap, a treaty starts,
K to ask with hopeful hearts,
L to end the whispered pact,
Events record each gentle act,
Lines and keys connect the parts.
