fix(words): close 12 type-drift errors from F2/F3/COLOR sprints

After the toggle-group structural migration `npm run check` still had
12 pre-existing errors. All from the active Words sprint (post-2026-05
F2/F3/COLOR work), not introduced by this session. Closes them to
restore green check:

- soma words.svelte: thread `onUploadImage` through the Provider opts
  (was required-undefined in WordsOpts but missing from the create()
  call).
- eidos words-toolbar-family-menu.svelte + words.svelte: add
  'insert-image' label to COMMAND_LABELS (the Record<WordsToolbarButton
  CommandName, string> required full coverage).
- eidos words.svelte: hoist the `leafItem` snippet out of <SomaWords.
  Provider> to template root level. Snippets defined INSIDE a component
  element are passed as named props in Svelte 5; this one was meant as
  a local helper. Also kills the "Expression too complex" error at the
  Provider tag — the leafItem prop was bloating the union.
- eidos words-drawer.svelte: extract 5 inline button-config arrays to
  typed `as const satisfies readonly { id: WordsCommandName; ... }[]`
  constants (FORMAT_MARKS, TEXT_ALIGN_ACTIONS, CELL_TONE_ACTIONS,
  CELL_VERTICAL_ACTIONS, CELL_TEXT_ALIGN_ACTIONS). The inline literals
  were inferring `id: string`, breaking `runCommand` and
  `activeMarks.includes`.

Result: npm run check 16 → 0 errors. Tests 658/658 pass.
