add server info screen, connection stats, and emoji picker

Server information (Monal-style): - Add ServerInformation model and ServerInfoView reachable from Settings, showing server software (XEP-0092), disco#info identities and features, conference (MUC) services via disco#items, and STUN/TURN via XEP-0215. - Add a curated XEP capability list with per-XEP success/error status derived from server/account disco features and connection flags. - Detect PEP (0163) from account disco pubsub#* features, HTTP Upload (0363) from the main domain plus its components, and add Roster Versioning (0237), Pre-Authenticated Roster Subscription (0379), and SASL SCRAM Downgrade Protection (0474, neutral because Martin does not expose SSDP). Connection statistics: - Add LumaConnectionStatsModule, an XmppStanzaFilter registered before stream management, to count sent / acknowledged / received stanzas. - Track last login and SMACKS session timestamps, and read SASL mechanisms and Client State Indication from the raw stream features. MAM / OMEMO handling: - Prefer a plaintext <body> fallback when OMEMO decryption fails instead of showing "failed to decrypt". - Keep the optimistic text of our own outgoing message when its echo cannot be decrypted back, instead of replacing it with a placeholder. Emoji picker: - Add EmojiCatalog and a cross-platform EmojiPickerView. - Open the picker for reactions (replacing the static quick list) and from the composer's smiley button, inserting the chosen emoji into the draft.
