2661 PR 3/3 Warship Manual Override, Aggro Override, and Heal-at-Port Command (#3501)

Part of [#2661](https://github.com/openfrontio/OpenFrontIO/issues/2661)
(split into 3 PRs so they are not too large..)

## Description:

Part 3/3 of
[#2661](https://github.com/openfrontio/OpenFrontIO/issues/2661).

This PR adds the retreat control and override behavior for warships:

- Manual override: moving a warship manually cancels retreat and
suppresses auto-retreat for 5 seconds
- Aggro override: a retreating warship will aggro a nearby enemy
transport or warship before continuing retreat
- Heal-at-port command for sending a warship to a friendly port manually
- Friendly-port validation for HealAtPortExecution
- Regression tests for manual override, aggro override, and heal-at-port
behavior



## 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

## Please put your Discord username so you can be contacted if a bug or
regression is found:
