feat(cms): U1 content model + migration scaffold for blog/news/events

Establish content/ as the source of truth for editable content and
back-fill it from the existing detail pages, per U1 of the no-code CMS
plan.

- docs/content-model.md: front-matter schema (EN/MK/SI), body_format
  html-vs-markdown, content/events -> projects/ output mapping.
- tools/migrate_pages_to_content.py: bs4/yaml extractor; pulls title,
  subtitle, category, ISO date (from ARTICLE_DATES), hero image+caption;
  preserves the article body PLUS trailing sibling sections (event
  galleries) verbatim as body_format: html. Reports unparseable pages
  instead of emitting half-formed files.
- content/**: 51 files (17 entries x EN/MK/SI), 0 skips.
- tools/tests/test_migrate_roundtrip.py: 12 characterization tests
  (structured fields, news-has-no-subtitle, event gallery/lightbox
  preserved, Cyrillic UTF-8 round-trip, every page parses).
- .gitignore: ignore __pycache__/ and *.pyc.

U1 is unblocked and standalone. U2 (render content -> pages) is next;
U5/U6 remain blocked on Open Question Q1 (Gitea<->GitHub topology).

+<p>If you are applying for or renewing a student residence permit in Slovenia, you must prove you have enough money to support yourself. That requirement is tied to Slovenia’s basic minimum income (osnovni znesek minimalnega dohodka).</p>
+<p>From 1 April 2026 this basic minimum income is €507,43 per month. This is the amount you should be ready to show for the whole academic year, most commonly through a parent’s written statement of support, or through other accepted proof such as a scholarship, bank funds, or student-work earnings.</p>
+<p>Because the figure follows the minimum income, it can change again. Always confirm the current official amount with your upravna enota (administrative unit) before you submit, and ask how they calculate the period and which evidence they accept.</p>

+<p>Ако аплицирате за студентска дозвола за престој во Словенија или ја продолжувате, мора да докажете дека имате доволно средства за издршка. Тој услов е врзан за словенечкиот основен износ на минимален доход (osnovni znesek minimalnega dohodka).</p>
+<p>Од 1 април 2026 овој основен износ на минимален доход изнесува 507,43 € месечно. Тоа е износот што треба да бидете подготвени да го докажете за целата академска година, најчесто преку писмена изјава од родител за поддршка, или преку други прифатени докази како стипендија, банкарски средства или заработка од студентска работа.</p>
+<p>Бидејќи износот го следи минималниот доход, може повторно да се промени. Пред да поднесете, секогаш потврдете го тековниот официјален износ кај вашата управна единица и прашајте како го пресметуваат периодот и кои докази ги прифаќаат.</p>

+<p>Če zaprošate za študentsko dovoljenje za prebivanje v Sloveniji ali ga podaljšujete, morate dokazati, da imate dovolj sredstev za preživljanje. Ta pogoj je vezan na slovenski osnovni znesek minimalnega dohodka.</p>
+<p>Od 1. aprila 2026 ta osnovni znesek minimalnega dohodka znaša 507,43 € na mesec. To je znesek, ki ga morate biti pripravljeni izkazati za celotno študijsko leto, najpogosteje s pisno izjavo staršev o podpori ali z drugimi sprejetimi dokazili, kot so štipendija, bančna sredstva ali zaslužek od študentskega dela.</p>
+<p>Ker znesek sledi minimalnemu dohodku, se lahko znova spremeni. Aktualni uradni znesek pred oddajo vedno preverite pri svoji upravni enoti in vprašajte, kako izračunajo obdobje in katera dokazila sprejmejo.</p>
