Evan 2794ab1270 feat: nuke-trail cosmetic effect + tabbed effects picker (#4466)
## What

Adds a **`nukeTrail`** cosmetic effectType alongside
`transportShipTrail`, so nukes leave a trail colored by their own
gradient/transition effect — independent of the boat-trail effect (a
player can run both). Also reorganizes the effects picker and store into
per-effectType **tabs**.

## Rendering

Boat and nuke trails are stamped into **one** trail texture keyed only
by owner, so independent coloring needs a per-tile unit-class signal:

- **Trail texture** `R8UI` → `R16UI`: texel = `ownerID(bits 0-11) |
nukeBit(bit 12)`. `TrailManager` stamps the bit (and preserves it when
repainting on unit death); the `Uint8Array`→`Uint16Array` ripple +
`UNSIGNED_SHORT` uploads flow through `GpuResources`, `TrailPass`,
`Upload`, `MapRenderer`, `Renderer`, `FrameData`.
- **Effect texture** widened to two stacked blocks
(`TRAIL_EFFECT_BLOCKS`): rows 0–7 = transportShipTrail, rows 8–15 =
nukeTrail. `writeEffectEntry(…, rowBase)`; `syncPlayerEffects` resolves
both effectTypes.
- **Shader** masks the owner, derives `rowBase` from the nuke bit,
offsets every row, and reuses the gradient/transition decode.
- Bonus: the 12-bit owner mask lifts the old `R8UI` >255-player
truncation.

## Schema / server / UI

- Shared attributes schema renamed `TransportShipTrail…` →
**`TrailEffectAttributesSchema`** (it's no longer ship-specific);
`NukeTrailEffectSchema` added to `EffectSchema` +
`CosmeticsSchema.effects`. `EFFECT_TYPES = [transportShipTrail,
nukeTrail]`.
- Server `Privilege`, selection, and the picker grid all iterate
`EFFECT_TYPES`, so they handle the new type with **no per-type code**.
- **Tabs:** the selection modal uses one tab per effectType
(`BaseModal`'s native tabs); the **store's** EFFECTS panel gets an
internal sub-tab bar (its top-level PACKS/EFFECTS tabs can't nest). Tabs
are always present, so a type you own entirely still appears as an empty
tab (previously the boat-trail section vanished from the store when you
owned everything).

## Review

A 3-angle adversarial review (bit-packing, type-ripple, GLSL/data-flow)
**refuted** the correctness concerns — the R16UI format, masking, and
block layout agree across `TrailManager` / shader / builder. The minor
survivors (a preview that only resolved boat trails, stale comments)
were fixed.

## Testing

- `tsc --noEmit`, ESLint, Prettier, `build-prod` — all clean.
- Schema/`Privilege` tests updated for `nukeTrail` (96 tests pass).
- The GL trail + tab UI are visual — not yet verified in a running game.
- The catalog (`cosmetics.json`, closed-source API) must ship the
`effects.nukeTrail` block for the effect to appear in production.
