feat(navigator): refresh the navigator with gradients, rows and quick join

[TheMeinerLP]

Summary

The navigator gets a four-row layout with a glass frame, a gradient per mode, lore that shows the player count against the known maximum, a quick join for minigames, and a server list in the same style. The server list is translated (it was English-only).

Layout

row 0   F F F F F F F F F
row 1   F . E . . . S . F      E = ElytraRace (11), S = Slender (15)
row 2   F . V . C . B . F      V = Survival (20), C = Creative (22), B = Build (24)
row 3   F F F F W F F F F      W = Spawn (31), replaces the frame pane in the middle

F = frame pane (light blue / cyan by row plus column parity), . = grey pane. A hidden entry leaves its slot grey.

Clicks

Click	Minigame (ElytraRace, Slender)	Server (Survival, Creative, Build)
Left	quick join	connect
Right	server list, always	connect (no hint line)
Shift-left or shift-right, portal exists	walk to portal	walk to portal
Shift, no portal	same as the unshifted click	connect
Any other click (number keys, Q, F, middle, double, drag)	nothing	nothing

Lore per entry: separator in the mode's gradient, Players 13 / 40 (maximum only when every service has announced its limit), blank line, then one ▸ KEY ACTION line per click. The portal line appears only when a portal exists.

Quick join rule

Among the minigame's running services, take those that are ready (limit announced) and not full. Pick the one with the most players; on a tie, the lowest name. Services are read again at click time. If none qualifies, the server list opens and shows why. With nothing running, the list is empty and says "No server is running right now." If the services cannot be read (no count provider, or the lookup fails), nothing opens and the player gets a chat refusal instead.

A pick in the server list reads the services again too, so a server that filled up or stopped since the list opened is refused rather than joined.

Behaviour change

A right click on a minigame used to walk to the portal (since #414) when a portal existed. It now always opens the server list, and the portal moved to shift-click. Players who used the right click for the portal need to shift-click.

Review fixes

• Only left and right clicks, with or without shift, act. Other click types are cancelled and do nothing, on minigames, servers and list entries.
• A failed or unavailable service read is no longer shown as an empty list.
• A pick is checked against a fresh read, not the list from when it opened.
• Tests for the ignored click types, the read failure and the stale pick were written first and failed on assertions before the fix. Picker listener counts stay constant across repeated opening, and stopping the module removes every opened list.

Menu variants

Kept the eight shared inventories (four permission combinations times two languages). The title is set per language when the module starts. Rejected two alternatives:

• GlobalTranslatedInventoryBuilder: Aves does not fire its click and close listeners for translated builders, so the module would have to forward them itself, as SwitcherInventory does.
• One inventory per opening: each open would register new listeners, and the leak tests would have to count openings instead of registrations.

The server list has one shared instance per minigame and language, with one builder per row count.

Other

• Bundles: 15 keys in messages_de.properties and messages_en.properties; a test checks both files against NavigatorMessages.KEYS.
• Removed DestinationPlayerLoreTest and DestinationClickHintLoreTest, which pinned the old lore API; NavigatorLoreTest and NavigatorClickHintTest cover that now.
• Updated cloudnet tests for the new slots and the four-row layout (NavigatorProtectionOrderingTest, SpawnReturnWiringTest, StandardLoadoutTest).

Test plan

• Pure tests written first: QuickJoinTest, ClickActionTest, NavigatorLayoutTest, NavigatorLoreTest, ServerPickerStyleTest, TaskCapacityTest, NavigatorMessagesTest.
• Environment tests: NavigatorRenderedLayoutTest (frame, slots, hidden entries), NavigatorClickHintTest, NavigatorServerPickerTest (quick join, server list, shift portal), and the existing permission, portal, telemetry and leak tests updated for the new slots.
• ./gradlew spotlessApply and ./gradlew build are green locally.
• Not yet checked on a running lobby: colours, and the German strings in the real client.
