## Description:
Current SAM behavior is to shoot a missile as soon as a nuke is in
range.
Players can exploit it by overshooting behind the SAM, so the SAM
missile will take way longer to reach the nuke, usually too late to
prevent its explosion.
This PR introduces a "smart" targeting system that allows SAM to
calculate an optimal interception tile along the nuke's trajectory. They
can also preshot before the nuke becomes vulnerable, as long as the
interception tile will be within the vulnerable window.
This change makes SAM range enforcement much more strict.
Changes:
- Nukes now precompute their full trajectory on creation and update
their current position index every tick.
- SAMs use this trajectory data and their own missile speed to calculate
the ideal interception tile.
- SAM missiles now aim directly at that interception point rather than
chasing the nuke.
Small changes on the fly:
- `BezierCurve` now uses a provided increment so the curve LUT is the
optimal size
- Increased nuke opacity when untargetable: 0.4 → 0.5
- Slightly extended nuke vulnerability range to SAMs: 120 → 150
===
Preshot an incoming nuke still in the unfocusable state. Notice how the
nuke is destroyed as soon as becomes focusable:

## Description:
Previously upgrading a unit would have it reload immediately, eg
upgrading missile silo 1=>2 gives it 2 missiles immediately. With this
change it must reload the missile. Same with SAMs. This prevents users
from spamming upgrades as missiles are coming in.
Fix the progress reloading bar. Previously it only showed the SAM/silo
as reloading when it was completely out of missiles. Now it shows
roughly how many missiles are available (eg level 5 fires 3 missiles,
now progress bar is at 40%). It also shows progress of missiles
reloading. If no missiles are available, progress bar is empty
There was a bug where if a silo of SAM was in cooldown it would be
updated each tick, causing the sprite/icon to be rerendered each tick.

https://github.com/openfrontio/OpenFrontIO/issues/776
I've implemented upgradable structures for cities and ports.
As of right now this is just meant as a QOL change for structure
stacking that currently happens and no gameplay changes are intended.
Structure upgrades cost the same as making a new structure of that type
and function the same as making a new structure of that type.
I'm putting up a draft PR for this now since adding support for SAMs and
Silos will take more time to handle the cooldowns and I want to make
sure I'm on the right track for getting this merged.
I also still need to add bot behavior for this and re-enable min
distance for structures.
I didn't see translations for the UnitInfoModal so I've left that out
for now.
I've tested locally in a single player game so far but will document and
test more thoroughly before merging.

## Description:
Currently, SAMs target any nuke within range. This can be frustrating
when a random SAM from another player intercepts your nuke, especially
since nukes follow a curved trajectory, leaving little room to adjust
their path.
This change modifies how SAMs intercept nukes: they will now only target
those whose impact points are near the SAM.
The “target range” is still generous, allowing players to defend against
Hydrogen bombs, while preventing random SAMs to intercept your valued
nukes.
In this example, the target was the opponent missile silo:

## Summary by CodeRabbit
- **Refactor**
- Unified and simplified how unit targets and cooldowns are managed
across all unit types, resulting in more consistent in-game behavior for
nukes, warships, trade ships, and SAM launchers.
- Updated naming and logic for unit targeting and cooldowns, improving
clarity in status displays and interactions.
- Reorganized unit interface and streamlined cooldown handling for
smoother gameplay experience.
- **Bug Fixes**
- Corrected visual indicators for nukes and warships to accurately
reflect their targets.
- **Tests**
- Updated automated tests to align with the new cooldown and targeting
logic.

## Description:
Improve type safety and runtime correctness by:
1. Enabling TypeScript's
[strictNullChecks](https://www.typescriptlang.org/tsconfig/#strictNullChecks)
compiler option.
2. Replacing all loose equality operators (`==` and `!=`) with strict
equality operators (`===` and `!==`).
3. Cleaning up of type declarations, null handling logic, and equality
expressions throughout the project.
Currently, the code allows implicit assumptions that `null` and
`undefined` are interchangeable, and relies on type-coercing equality
checks that can introduce subtle bugs. These practices make it difficult
to reason about when values may be absent and hinder the effectiveness
of static analysis.
Migrating to strict null checks and enforcing strict equality
comparisons will clarify intent, reduce bugs, and make the codebase
safer and easier to maintain.

changed the sam cooldown to be a general cooldown function and added a
missilesilo cooldown
The function either adds the current tick as the starting point of the
cooldown or sets the cooldown to null and updates the unit. That way
getcooldown function can be used to get back the tick the cooldown was
started and can be compared to the cooldown set in the config.

when an building is taken over by another player the execution for it
doesnt change its owner this makes it so when a sam is captured it tries
to intercept your own nukes and doesnt intercept the ones by the
previous player
this change makes executions of buildings automaticly switch their owner
added a unitgrid instead of a defensepostgrid for all units to be able
to see if a tile is inside the range of a unit by a custom distance
this is used for the sam launcher to draw a circle around the area it
protects
removed all parts that use the defensepostgrid and made it use the
unitgrid instead
More costly (start at 1.5M), increase cost cap (4.5M), biggest timeout
(5s->10s), much lower chance to stop hydrogen (70%->10%), triple
construction time (10s->30s) otherwise it's trivial to build a SAM right
before a nuke hits
