Move custom String functions into default string library

[speed2CZ]

Ive changed this PR to contain only the changes to strings. Vectors will get a new PR once it's more polished.

Changes

• All custom String_ functions are moved to the default string. Same pattern as the extended table.
• Removed imports of the utils.lua file, as this is a global file and doesnt need to be imported. When it does, it is actually redefining the globals.

Checklist

• Changes are annotated, including comments where useful
• Changes are documented in a changelog snippet according to the guidelines.
• Request 2-3 reviewers from the list of reviewers and their areas of knowledge.

Summary by CodeRabbit

• New Features

  • Added a standardized string library API for common text operations, including splitting, joining, capitalization, formatting, and prefix/suffix checks.
  • Added a Restart Session option to the quit dialog when available.
  • Retained compatibility with existing string helper names.

• Bug Fixes

  • Fixed scenario setup logic that could prevent faction configuration from completing correctly.

• Tests

  • Updated string utility tests to cover the standardized API.

📝 Walkthrough

Walkthrough

The change moves custom string helpers into the default string namespace, updates call sites and tests, preserves deprecated global aliases, and adds a conditional Restart Session action to the escape dialog.

Changes

String API namespace migration

Layer / File(s)	Summary
String namespace implementation lua/system/config.lua, lua/system/utils.lua	String helpers now use the string namespace. Deprecated global aliases preserve compatibility. String metatable cleanup is deferred to lua/system/utils.lua.
Engine and simulation call sites lua/WeaponPriorities.lua, lua/keymap/*, lua/sim/*, lua/ui/game/gamemain.lua, lua/ui/maputil.lua	Parsing and prefix checks now call namespaced string helpers.
UI call-site migration lua/ui/dialogs/createunit.lua, lua/ui/lobby/*	UI formatting, parsing, extraction, and capitalization now use namespaced string helpers. Unused utility imports were removed.
String API validation and release notes tests/utility/string.spec.lua, changelog/snippets/other.7250.md	Tests use the new API names, and the changelog documents the migration.

Session restart dialog

Layer / File(s)	Summary
Conditional restart action lua/ui/dialogs/eschandler.lua	The quit dialog shows a Restart Session button when the session is active and restartable. The dialog option is renamed to OnlyWorldCover.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to d834b

The quit dialog loses established keyboard controls, and its new restart action is untranslated. The keyboard regression should be fixed before merge.

Explanation

The description explains the string-library migration, removal of redundant utils.lua imports, and the scope exclusion for vectors. It includes the checklist and confirms the changelog and reviewer requirements. It does not provide a dedicated testing section or additional context section, but the description is otherwise relevant and sufficiently complete.

Overall idea is good, but it lacks scope and finesse. Vector mustn't know about terrain at all. Most of vector functions can be moved into its meta with engine patch where it will be way more performant, including string ones.

I made an issue before FAForever/FA-Binary-Patches#93

Add a localization key to the restart label.

The other dialog labels use <LOC ...>. QuickDialog passes button labels to CreateText, which resolves localization markers. This bare label has no locale-specific key, so non-English users see English. Add the assigned localization marker. (raw.githubusercontent.com)

Keep the quit dialog keyboard-modal.

OnlyWorldCover = true skips MakeInputModal. Popup still routes Escape to its no-op OnEscapePressed, and Enter has no handler. Remove OnlyWorldCover or set it to false.
