chore(gui): rebrand — strip TG/Boosty/Patreon/feedback-bot, keep CC BY-NC-SA attribution

The previous feature/gui-rebrand-polish work only updated the appInfo store
keys; Footer.svelte, settings, and the commands page were still rendering
upstream's Telegram channel, Boosty/Patreon support links, feedback bot,
and the original author byline. This finishes the job.

Rust side (applies after `cargo build` — currently a no-op until MSVC Build
Tools are reinstalled):
- Cargo.toml: authors = ["Bossiara13"], repository = J.A.R.V.I.S-rust fork.
  Original attribution stays in LICENSE.txt per CC BY-NC-SA 4.0; the UI
  no longer renders an author byline.
- config.rs: dropped TG_OFFICIAL_LINK / FEEDBACK_LINK / SUPPORT_BOOSTY_LINK
  / SUPPORT_PATREON_LINK. Added UPSTREAM_REPOSITORY_LINK (Priler/jarvis for
  the licence attribution), ISSUES_LINK (this fork's GH issues), and
  PYTHON_FORK_LINK.
- tauri_commands/etc.rs: dropped get_tg_official_link/get_boosty_link/
  get_patreon_link/get_feedback_link. Added get_upstream_link, get_issues_link,
  get_python_fork_link. Tidied up the Option<&str> -> String boilerplate
  with unwrap_or.
- main.rs: invoke_handler updated to match.

Frontend side (visible only after Rust rebuild — Tauri bundles the dist into
the exe):
- stores.ts: appInfo shape reduced to repositoryLink / upstreamLink /
  issuesLink / pythonForkLink / logFilePath. loadAppInfo() uses fetchOr()
  with hardcoded fallbacks so the UI still populates correctly when run
  against an un-rebuilt binary; fetchRepoOr() additionally overrides
  CARGO_PKG_REPOSITORY if it still resolves to upstream's Priler/jarvis.
- Footer.svelte: rewritten — © year + "J.A.R.V.I.S." + repo link + issues
  link + small "fork of Priler/jarvis · CC BY-NC-SA 4.0" attribution line.
  No author byline (it's in LICENSE.txt).
- routes/settings/index.svelte: feedback link now points to GitHub Issues.
- routes/commands/index.svelte: TG-channel reference replaced with a link
  to the Python fork (where the command builder lives) plus a pointer to
  resources/commands/ in this repo. Bruh GIF removed.
- locales/{ru,en,ua}.ftl: removed footer-author / footer-telegram /
  footer-support, added footer-issues / footer-fork-of, rewrote
  commands-wip-* strings, retargeted settings-beta-bot to "GitHub Issues".

Bundle identifier (com.priler.jarvis) kept intact to avoid moving the app
data directory.
