Add Php cs fixer

[lachlan-00]

You'd mentioned function ordering in my last pull so i'm adding in php-cs-fixer to require-dev

I've added rules i think you'd want

Changes from the rules are

• gitattribute line endings set in dc12142
• line_ending (added , at the end of array items)
• ordered_class_elements has set visibility and alpha sort on functions with no other changes

no functional changes but i could also add scripts to composer so you can run these commands from composer which i use a heap (e.g. composer cs:fix, composer cs:check)

You could also set cs analysis on the repo for pulls, etc but in this pull i've really just decided to set the rules and apply them.

Pull request overview

This PR introduces PHP-CS-Fixer to the project’s dev toolchain and applies formatting-oriented reordering/cleanup across a few PHP files (primarily ordering of class elements), with the intent of standardizing style and enforcing consistent function ordering going forward.

Changes:

• Add friendsofphp/php-cs-fixer to require-dev and introduce a project-level .php-cs-fixer.php configuration.
• Apply php-cs-fixer-driven ordering changes to source and test files (method/property ordering, minor formatting).
• Add Git settings updates for line endings and ignore the php-cs-fixer cache file.

why not per 3.0?

why not per 3.0?

I just copied my existing file from Ampache and updated to remove specifics there. The changes implemented by the rules specifically are 2 trailing commas on multiline.

I've added @PER-CS3x0 with bbdf276 and that's only changed some minor spacing as well
