The Entity column in the Documents tab now displays a single bold
colored letter (A/I/M/P/Q/V) followed by the entity name. Each
entity kind maps to a distinct Wong palette color:

  A appliance (rose), I incident (vermillion), M maintenance (orange),
  P project (sky blue), Q quote (green), V vendor (yellow)

The letter is rendered independently from the name so highlight,
deleted, and dimmed states are handled correctly per-span.

Pressing enter on the Entity column in the Documents tab now navigates
to the linked entity's tab (e.g. P -> Projects, V -> Vendors). The
target tab is resolved dynamically from the kind-letter prefix since
the entity column is polymorphic. Unlinked documents show "Nothing to
follow."

The edit key (i) still opens the inline entity selector for
reassignment.

Replace the visible letter prefix with whole-name coloring: entity
names in the Docs tab are now colored by kind (project=accent,
vendor=warning, etc.) without a leading letter. The internal cell
value still carries the kind-letter prefix for linking and pinning.

Pinning on the Entity column now groups by entity kind (e.g., all
projects) rather than individual entity text, making it easy to
filter by category.

The Entity column spec was missing Kind: cellEntity, so Enter fell
through to the "Press o to open" fallback instead of navigating to
the linked entity. Set the kind on the spec so handleNormalEnter
matches the entity branch, and add the link arrow (→) to the column
header and status bar hints.

…ptions

UpdateDocument was omitting EntityKind and EntityID from the SQL
update, silently dropping any entity assignment changes. Remove
those columns from the omit list so reassigning or clearing an
entity link persists to the database.

Also color entity selector option labels by kind (matching the
table column palette) and drop the redundant [category] suffix.

Set Height(10) on all entity select fields so the option list scrolls
within a fixed window instead of overflowing the terminal.
