Mauricio Siu ff275fe94e fix: sync terminal size with backend PTY, avoid connecting with placeholder container ID
Fixes #5092 — typing in the database/docker terminal overwrote text
instead of continuing on new lines. The xterm.js client never told the
backend PTY its actual size (node-pty/ssh2 always defaulted to 80x24
and were never resized), so whenever the rendered terminal width
differed from that, the remote shell's cursor math diverged from what
the client displayed.

- docker-container-terminal.ts / terminal.ts: pass the client's initial
  cols/rows into node-pty spawn and ssh2 exec/shell, and resize the PTY
  on a {type:"resize"} control message sent over the same ws channel.
- docker-terminal.tsx / settings/web-server/terminal.tsx: send cols/rows
  on connect and on every term.onResize, and watch the container with a
  ResizeObserver to refit on dialog/window resize.

Also fixes two related terminal/logs bugs surfaced while testing this:
- docker-terminal.tsx no longer opens a connection with the
  "select-a-container" placeholder ID before a real container is
  selected, and defers terminal creation a frame so React StrictMode's
  dev-only phantom mount doesn't hit a known xterm.js dispose race
  (xtermjs/xterm.js#5011, "Cannot read properties of undefined
  (reading 'dimensions')").
- docker-logs-id.tsx (shared by application/compose/compose-stack logs)
  had the same placeholder-ID issue, surfacing Docker's raw
  "No such container: select-a-container" daemon error instead of a
  proper empty state.
