fix: every text field has a limit, and long names no longer overflow

A Pomodoro profile's name could be as long as one liked, and pushed the
Home card's header beyond the window. Of 56 fields, only release notes and
a licence's year had a limit.

Limits by what a field holds (core/widget/text_limits.dart, decided
2026-10-11): a name shown in a menu or on a chip 40 (Pomodoro profiles,
tags, a study button's label); a secondary title or a reading above
characters 60; a title 120 (studysets, notes, paths, steps, PDFs,
callouts, a video's caption, a licence's holder); an answer or item 200
(meanings, readings, glosses, options, categories, gaps, typed answers);
a search 200; a part of a citation 500; a message 2000 (reports, replies,
questions to Claude); a web address 2000; a passage with gaps or a
formula 5000. The public profile and a published studyset's name take the
instance's own limits (display name 30, handle 30, bio 500, links 2000,
name 50), which the app didn't say before. Pasted flashcards to import and
numbers have none. Fields count only from 80 % of their limit.

Text can still be longer where it came from elsewhere (an older app, an
import, a release), so the places showing it cut it short: the Pomodoro
card's header and its profiles. A test shows names beyond every limit on
Home, the library, a studyset's screen with its tabs and topics, the card
browser with its tags, and a session, on a phone and a desktop: none
overflows (it fails on the Pomodoro card as it was).
