strings: browse every string in the binary and jump to it (IDA's Shift+F12)

ida-pro-mcp exposes no full strings list (only a filtered/capped "interesting"
survey), so this is a new injected tool plus a filterable browser.

* server/patch_server.py: list_strings(offset,count,min_len,refresh) — every
  literal from idautils.Strings() as {addr,text,len,type}, paginated, with a
  module-level cache keyed by min_len (rebuilding is O(n) and the browser pages
  the whole list).
* domain: StrLit dataclass + Program.strings() — pages the full list once and
  caches it.
* app: StringsPalette modal (mirrors SymbolPalette) — case-insensitive substring
  filter with the match highlighted, addr/len/text columns, ↑↓/Enter/Esc.
  Bodies are sanitized to one printable line (\n/\r/\t escaped, non-printables
  dropped, long strings clipped) so control chars can't break the layout;
  display strings are pre-rendered+pre-lowered once since filtering runs per
  keystroke. Enter jumps to the literal in the unified listing via _goto_ea.
  Bound to '"' and Shift+F12, plus a "Strings…" command-palette entry.

Verified on echo: 150 strings listed with addr/len/text, filtering 'usage'
narrows to 2 (case-insensitive), Enter lands the listing cursor on the literal.
Pilot `strings` scenario 6/6; full suite 165/2-flake.
