move handler methods into ParserMode classes and rename Handler

Each ParserMode class now implements handle() from ModeInterface,
containing the token handling logic that previously lived as individual
methods on Doku_Handler.

The Handler class (formerly Doku_Handler) is the single dispatch point:
Lexer passes tokens to Handler::handleToken() which routes to mode
objects, plugins, or returns false. The Lexer only tokenizes and
resolves mapHandler aliases.

Key changes:
- Add handle() to ModeInterface, implemented by all mode classes
- Move Doku_Handler to dokuwiki\Parsing\Handler namespace
- File extends Code (shared parsing via $type property)
- Quotes uses mapHandler() + Handler::getModeName() for sub-modes
- Media::parseMedia() replaces Doku_Handler_Parse_Media()
- Code::parseHighlightOptions() replaces parse_highlight_options()
- Per-parse state (footnote, doublequote) stays on Handler
- Deprecated wrappers kept for base/header/internallink/media
- Class alias and rector rules added for backward compatibility

introduce ModeRegistry to encapsulate parser mode categories

Replace the global $PARSER_MODES definition in inc/parser/parser.php
with a ModeRegistry singleton that initializes and manages the mode
categories. The global array is still populated for backward
compatibility with plugins that access it directly.

Mode constructors now use ModeRegistry::getModesForCategories()
instead of accessing the global directly. p_get_parsermodes() and
p_sort_modes() are moved to inc/deprecated.php as thin wrappers.

mark nullable types explicitly

PHP 8.4 will throw a warning where type hints without a ?prefix are used
and nullable parameters can be passed.

I'm not sure if I found all occurances, but we still rarely use type
hints, so it might not be many indeed.

Remove the htmlok and phpok embedding options

Both options have grave security implications and novice users seem to
ignore advice about them. In the last decades I never came across a wiki
that had legitimate use of these options.

If someone needs the functionality, it can easily be added back using a
plugin. But I prefer to give users one less option to shoot themselves
in the foot.

Removal of the translations for the config strings can follow after this
has been merged.
