Add linetags and indent support for formatted text

[brrichards]

Summary

• Add support for ordered list, check list, code-block, block-quote on LineTag
• Add optional indent field for StringLineAtom - Quill intercepts tab input and converts it to a "\t" delta insert which works already. When intercepting a tab on a line with a line tag Quill sends the indent with the line tag change. This requires StringLineAtom to hold indent value
• Updated the currentViewSchema to reflect new fields. Updated the minversion for collab test to reflect new schema.

Files Changed

• textDomainFormatted.spec.ts - updated compatibility test
• textDomainFormatted - add new fields onto StringLineAtom
• textEditor.test.tsx - add tests for indent
• quillFormattedView.tsx - update parseLineTag and delta logic to deal with new optional StringLineAtom.indent field

Pull request overview

This PR extends the formatted-text (tree-based) schema and the Quill integration to support additional line-level formatting (more LineTag variants) and to persist Quill’s line indent information on StringLineAtom.

Changes:

• Extended FormattedTextAsTree.LineTag to include ordered lists, checklists, block quotes, and code blocks, plus added optional indent to StringLineAtom.
• Updated Quill ↔ tree conversion logic to emit/consume the new line tag variants and to round-trip indent when present.
• Updated schema compatibility snapshot/version and added tests for parseLineTag null-handling and indent emission.
