Subject: [PATCH 1/4] feat: add indestructible red creative wall

The creative wall stays a normal destructible target (biters path to it,
asteroids hit it) but is healed to full on every hit via a name-filtered
on_entity_damaged handler, so it can never be destroyed. max_health is bumped
high as defense-in-depth. The wall and its item icon are tinted red to match
the mod's other creative entities. Not Space-Age gated.

The on_entity_damaged handler is registered with event filters and excluded
from the generic filterless event loop; Phase 3 (asteroid protection) will
extend this same handler rather than registering a second one.

     - Add an admin-only Surface tab. Admins can create a new blank surface by typing a name; the surface immediately appears in the Surface Cheats target list for every connected player allowed to see other surfaces.
     - Add space-platform creation to the Surface tab (Space Age only). Admins can type a name and pick the planet to orbit; the platform comes up with a hub already placed and its surface immediately appears in the Surface Cheats target list.
     - Add planet-surface creation to the Surface tab (Space Age only). Admins can pick a planet and create its surface; if the surface already exists the action is a harmless no-op, and any newly created surface immediately appears in the Surface Cheats target list.
+    - Add a creative wall: an indestructible red wall. Enemies still target and attack it, but it instantly heals back to full and can never be destroyed. It works on any surface, including space platforms, and is enabled by the normal Creative tools' recipe sweep.
   Changes:
     - Move the Surface Cheats menu from the Cheats tab into the Surface tab, grouping it with the surface-creation tools.

Subject: [PATCH 2/4] feat: add self-fueling creative thruster (Space Age)

A clone of the vanilla thruster that keeps the normal performance curve but has
its fuel + oxidizer topped off every tick by script, so a space platform travels
at vanilla speed with no fuel chain to supply. Defined only when Space Age is
present (its fluids are space-age-only); the entity is cloned in data-final-fixes
where the vanilla thruster prototype is guaranteed to exist.

The body and item icon are tinted red to match the mod's other creative
(spawn/source) entities; exhaust flames/glow are left natural.

Subject: [PATCH 3/4] fix: drop patchy thruster body tint, mark creative
 thruster by red icon only

The thruster's animated body doesn't take a flat tint cleanly (only the
integration patch picked it up, leaving a half-red look). The creative variant
is now distinguished solely by its red item icon.

Subject: [PATCH 4/4] feat: add global asteroid spawning rate cheat (Space Age)

Add an 'Asteroid spawning rate' numeric input to the Game Settings cheats
submenu, exposing game.map_settings.asteroids.spawning_rate directly (a float
multiplier, default 1; set 0 to stop all asteroid spawning). Modeled on the
existing game_speed numeric cheat and clamped to >= 0. Applies game-wide with
zero runtime cost - no event handler, no per-tick work. Gated to Space Age via
get_player_can_access_function, so the row is hidden on vanilla.

Replaces the originally planned per-surface on_entity_damaged asteroid-protection
toggle, which playtesting showed was redundant (creative walls block asteroids
fully; remove/kill all enemies clear them).

     - Add planet-surface creation to the Surface tab (Space Age only). Admins can pick a planet and create its surface; if the surface already exists the action is a harmless no-op, and any newly created surface immediately appears in the Surface Cheats target list.
     - Add a creative wall: an indestructible red wall. Enemies still target and attack it, but it instantly heals back to full and can never be destroyed. It works on any surface, including space platforms, and is enabled by the normal Creative tools' recipe sweep.
     - Add a creative thruster (Space Age only): a thruster that refuels itself every tick, keeping a space platform travelling at vanilla speed with no fuel or oxidizer chain to supply. Place it on a platform, set a route, and it travels with no fuel management.
+    - Add an "Asteroid spawning rate" input to the Game Settings cheats (Space Age only): a global multiplier for how often asteroids spawn around space platforms. Default is 1 (vanilla); set it to 0 to stop asteroids spawning entirely. Applies game-wide, not per surface.
   Changes:
     - Move the Surface Cheats menu from the Cheats tab into the Surface tab, grouping it with the surface-creation tools.
