[MDS-6987] Add Figures and Documents to Condition Data Variable Menu

MDS-6987

Why are you making this change? Provide a short explanation and/or screenshots

To allow permitting inspectors to more easily work with permit package references, the Condition Data Variable (CDV) Menu is to be updated to allow inspectors to insert permit package references into condition text when drafting the permit, so that the references remain accurate when permit package files are reordered or replaced.

• Commit 1 Removed old CDV menu code and Flagsmith gating - moving forward we only use the 'new' CDV picker without any Flagsmith gate (Cleanup).
• Commit 2 Add new Flagsmith Flag for this functionality.
• Commit 3 Moved logic for determining permit-package ordering into single helper/utility function, updated unit tests accordingly and pointed all files that need this functionality to use the new helper. Added 'Permit Package files -> Figures/Documents' to CDV menu, gated by feature flag (these selections insert 'tokens' for the permit package files into the condition text)
• Commit 4 Replaced the original Permit Condition 'plain text area' with a react-quill editor for the PermitConditionForm's condition filed (this is UI only), which includes a custom Quill embed blot that renders the 'label' (green or red 'pill' of Doc/Fig index and title) for an inserted Figure/Document reference. Small fix to preamble text area (keep using original textarea, not rich-text Quill editor) and run a WGAC pass on the changes using Claude
• Commit 5 Added comment regarding preservation of GUID, for when 'Archive/Replace' functionality is implemented (risk of breaking the CDV references if guid is not maintained)
• Commit 6 Added helper/utility function that checks if a Figure/Document is actually being referenced in any permit condition, used to warn users if they try to remove a file from the permit package that it will break the reference - also added unit tests for this new functionality
• Commit 7 - Bug Fix Fixed bug where copying and pasting condition text introduced a series of errors - related to not having a unique CSS/className attribute on the 'pill' elements
• Commit 8 - UX Improvement Updated 'this figure/doc is referenced' warning to fire immediately after trying to de-select the 'part of permit package'checkbox, instead of before trying to save
• Commit 9 Ensured that issued permits correctly resolve Figure/Document references - they appear as the literal index (1.2, 1.3, etc) and title - not in a 'pill'. If a removed reference is included, it gets the literal text of 'Reference unavailable'.
• Commit 10 Minor patches for es-lint warnings and overall code improvements + cleanup
• Commit 11 Claude Pass: Refactor @lru_cache to instead determine locked doc value once, and pass through rather than global cache
• Commit 12 Fix failing unit tests
• Commit 12 Resolve PR comments: Fix typo, update backend logic to determine the '1.1' locked row to match the frontend logic (and relevant unit tests), move variable substitution to before token extraction to avoid variable naming collisions, turn getPermitPackageFilesByType into an interface for proper typing
