fix(aasystem): refresh unpack menu and fix unit overlap after assembly

[FullGas1]

Summary

• Stale F10 unpack menu after AA system assembly: _assemble() called CTLDCrate:destroy() directly, bypassing CTLDCrateManager. OnCrateCleared was never published, so _refreshNearbyPlayers never fired and the unpack submenu stayed visible. Fixed by routing through CTLDCrateManager:destroyCrate().
• Overlapping units on spawn (S-300 TEL D + Big Bird SR at 240 deg): The arc-step formula used arcRad/partAmount (full circle) instead of arcSegment/partAmount (part's reserved segment). Fixed in _buildSpawnArrays.

Fixes both bugs reported during field testing of the S-300 (SAM long range). Covers all AA systems -- both code paths are generic.

Test plan

• New busted L1 test: S-300 _buildSpawnArrays -- all positions pairwise-distinct (>=1 m apart)
• New busted L1 test: S-300 _assemble -- OnCrateCleared published 5x (one per consumed crate)
• Existing deploy_managers_spec F-021 updated to register crates in CTLDCrateManager (required by new destroy path)
• 1066 unit + 194 functional tests green
• CTLD.lua rebuilt

Summary by Sourcery

Fix AA system unpack behaviour by refreshing the F10 unpack menu after assembly and correcting spawn geometry to prevent overlapping units.

Bug Fixes:

• Ensure consumed AA system crates are destroyed via CTLDCrateManager so OnCrateCleared is published and the F10 unpack submenu refreshes for nearby pilots.
• Correct AA system spawn angle computation so multi-unit parts are distributed within their reserved arc segment and no units overlap on spawn.

Enhancements:

• Register test crates with CTLDCrateManager in assembly tests to cover the new destruction path.

Documentation:

• Document the AA system unpack bugfixes and their rationale in the changelog and backlog PRD/tickets.

Tests:

• Add unit tests verifying S-300 spawn positions are pairwise distinct and that _assemble publishes OnCrateCleared once per consumed crate.
• Update existing deploy manager assembly tests to use CTLDCrateManager for crate registration.

Reviewer's Guide

Routes AA system crate destruction through CTLDCrateManager to ensure OnCrateCleared is published (refreshing the F10 unpack menu) and corrects the spawn geometry in _buildSpawnArrays so multi-unit parts are distributed within their arc segment; adds focused unit tests, backlog documentation, and changelog entries for the FIX-AASYSTEM-UNPACK-BUGS work.

File-Level Changes

Change	Details	Files
AA system assembly now destroys crates via CTLDCrateManager so OnCrateCleared is published and the F10 unpack menu refreshes correctly.	_assemble now acquires CTLDCrateManager instance and uses destroyCrate(crateName) instead of calling crate:destroy() directly for each consumed part crate. Assembly tests register AA crates inside CTLDCrateManager to match the new destroy path and reset crate manager state in setup/teardown. New unit test for _assemble stubs EventDispatcher:publish and asserts OnCrateCleared is fired once per consumed S-300 crate.	CTLD.lua src/CTLD_aasystem.lua tests/ci/unit/deploy_managers_spec.lua tests/ci/unit/aasystem_spec.lua
AA system spawn geometry is fixed so multi-unit template parts (e.g. S-300 TEL D) no longer overlap other units when spawned.	_buildSpawnArrays now computes an arcSegment per part (2π/partCount) and uses step = arcSegment/partAmount, with angles anchored at arcBase, instead of spreading units over the full circle. New S-300-specific geometry test builds systemParts from the S-300 template, calls _buildSpawnArrays, and asserts all spawn positions are pairwise-distinct with a 1 m tolerance.	CTLD.lua src/CTLD_aasystem.lua tests/ci/unit/aasystem_spec.lua
Documentation and backlog entries capture the FIX-AASYSTEM-UNPACK-BUGS work and its scope.	CHANGELOG adds a Fixed section describing the AA system unpack menu and spawn overlap fixes. Backlog README gains a FIX-AASYSTEM-UNPACK-BUGS entry summarizing the issue. New PRD and ticket markdown files describe problem statement, solution, and acceptance criteria for spawn geometry and menu refresh bugs.

Hey - I've left some high level feedback:

• In the CTLDCrateAssemblyManager _assemble publishes OnCrateCleared per consumed crate spec, you restore EventDispatcher.getInstance().publish using a fresh getInstance() call; consider storing the original EventDispatcher.getInstance() object in before_each and restoring publish on that same instance in after_each to avoid subtle bugs if the singleton instantiation logic ever changes.
• The S-300 template lookup logic is duplicated between buildS300Parts() and the _assemble publishes OnCrateCleared test; extracting a shared helper for fetching the S-300 template would reduce repetition and keep the tests easier to maintain if template names or layout change.

## Overall Comments
- In the `CTLDCrateAssemblyManager _assemble publishes OnCrateCleared per consumed crate` spec, you restore `EventDispatcher.getInstance().publish` using a fresh `getInstance()` call; consider storing the original `EventDispatcher.getInstance()` object in `before_each` and restoring `publish` on that same instance in `after_each` to avoid subtle bugs if the singleton instantiation logic ever changes.
- The S-300 template lookup logic is duplicated between `buildS300Parts()` and the `_assemble publishes OnCrateCleared` test; extracting a shared helper for fetching the S-300 template would reduce repetition and keep the tests easier to maintain if template names or layout change.
