Fix chapter order, and cover more words without more data

Chapter order: Golestan's دیباچه was rendering below the eight باب because the
listing drew every child category and then every poem. ganjoor.net interleaves
them — a book's preface first, then its chapters, then its remaining poems, so
Hafez reads مقدّمه, five collections, مثنوی, ساقی‌نامه. Ganjoor decides this
with each poem's MixedModeOrder (1 above the chapters, 0 below), which the
exported _cat.json doesn't carry and the live API only exposes one poem at a
time, so prefaces are matched by title for now. Adding MixedModeOrder to the
Poems entries in ganjoor-data would make it exact.

Coverage: I went looking for Arabic and Urdu Wiktionary and measured them
instead of assuming. Against 1,285 distinct words from thirteen poems, Urdu
added nine words and Arabic could reach at most five — the uncovered words
were never Arabic, they were Persian morphology the lookup didn't handle:
enclitic pronouns (آیدت, باشدش, تربتش), negation stacked on a prefix
(برنیاید), and compounds. Deepening the affix chain to two passes takes 87% to
91% with no new data at all, so neither dictionary ships.

Each definition now names its language pair rather than just its source, so a
reader can tell what they are looking at.

Dropped the selection-toolbar lookup: Compose 1.10 stopped routing
SelectionContainer through LocalTextToolbar, so a custom toolbar is never
asked to show, and the replacement in foundation's contextmenu package is
internal. Tapping a word already does the lookup; the note in PoemScreen says
when to revisit.

Verified on an API 36 emulator: Golestan lists دیباچه first, and tapping
نافه‌ای resolves through its affix to ناف with both sources labelled.
