perf(ui): switch UI layers to wall-time tick intervals (#3025)

## Description:

Preparatory change for the upcoming “unbounded worker” work: 
decouple expensive UI layer updates from game tick frequency by moving
UI ticking to wall-clock intervals. This reduces redundant UI work when
the simulation runs faster than real time (notably replays /
singleplayer at speed > 1) while keeping the UI responsive and
predictable.

## Changes:

- Add optional `Layer.getTickIntervalMs()` and enforce it in
`GameRenderer.tick()` using wall-clock time.
- Convert key UI layers from tick-modulus gating to fixed intervals:
  - `ControlPanel`: 100ms
  - `GameRightSidebar`: 250ms
  - `MainRadialMenu`: 500ms
  - `Leaderboard`, `NameLayer`, `ReplayPanel`, `TeamStats`: 1000ms


## Please complete the following:

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