fix: Settings crash, photo preview before sending, incoming-content hardening
Settings crashed with a TypeError: the profile card passed a SepotFingerprint object where the localized string formatter expects a String (hidden behind a `dynamic` parameter). Also fixes RangeError in avatar initials (empty names, double spaces) and switches initials to grapheme clusters so emoji don't get split. New photo preview screen: a captured or picked photo no longer sends immediately — it opens in a preview with freehand drawing (7 colours, undo), draggable text overlay, 90° rotation and a caption field. Nothing leaves the device until Send is tapped. Incoming-content hardening: decryption and content processing are now separated in the delivery path. Once an envelope is decrypted the ratchet has advanced, so redelivery can never help — permanently malformed content (FormatException/TypeError) is acked and dropped instead of poisoning the queue on every reconnect. Attachment metadata now validates base64 of the crypto fields up front, and a corrupt inline thumbnail no longer breaks bubble rendering. PNG without real transparency (screenshots, edited photos) is now re-encoded as JPEG — several times smaller on the wire. Tests: 116 (new widget tests for Settings and the photo preview, AttachmentMeta wire validation).

## [Nevydáno]
|
||||
|
||||
### Přidáno
|
||||
- **Náhled fotky před odesláním.** Vyfocená nebo vybraná fotka už
|
||||
neodchází okamžitě — otevře se náhled, kde jde fotku otočit, kreslit
|
||||
po ní prstem (7 barev, krok zpět), přidat na ni text (tažením se
|
||||
přesouvá, klepnutím upraví) a připojit popisek. Odejde až po klepnutí
|
||||
na Odeslat; zavření náhledu nic nepošle.
|
||||
|
||||
### Opraveno
|
||||
- **Nastavení se nevykreslilo** — obrazovka místo obsahu ukazovala
|
||||
chybovou hlášku „Tahle obrazovka se nevykreslila". Profilová karta
|
||||
předávala do překladu otisk klíče jako objekt místo textu.
|
||||
- Avatar s iniciálami spadl na prázdném jménu nebo jménu s dvojitou
|
||||
mezerou; iniciály se nově skládají po grafémech, takže nerozpůlí emoji.
|
||||
- **Písma se dodávají v aplikaci** (Inter, JetBrains Mono — OFL).
|
||||
Aplikace dřív stahovala fonty za běhu z Google CDN — síťový požadavek
|
||||
na cizí server navíc a binárka odlišná od zveřejněného zdroje.
|
||||
- **Trvale vadná příchozí zpráva už neotravuje frontu.** Zpráva, jejíž
|
||||
obsah nejde po dešifrování zpracovat (poškozená pole od upraveného
|
||||
klienta), se potvrdí a zahodí — dřív se doručovala donekonečna při
|
||||
každém připojení. Nedešifrovatelné obálky fronta dál drží.
|
||||
- Příloha s poškozeným náhledem od protistrany shodila vykreslení
|
||||
bubliny; vadný náhled se nově zahodí při příjmu a base64 krypto polí
|
||||
příloh se validuje.
|
||||
- Zachycení výměny důvěryhodního kořene relaye (signál MITM) na
|
||||
pozadí — dřív tichá neošetřená výjimka, teď příznak čitelný pro UI.
|
||||
- PNG bez průhlednosti (screenshoty, upravené fotky) se posílají jako
|
||||
JPEG — několikanásobně menší přenos; PNG zůstává jen pro obrázky se
|
||||
skutečnou průhledností.
