fix(calendar): redact script diagnostics, and page the calendar list

Three findings from CodeRabbit, all valid.

Raw subprocess output was being returned to the client -- the script's
stderr on one path, and its own error payload on another. CodeQL flagged
the same line. That script handles OAuth client secrets and interpolates
exceptions into its messages, so either could carry a secret or a path.
Both now go to the log unredacted, where they are worth having in full,
and reach the client through a redactor.

That redactor already existed inside describe_exception, which only
takes exceptions. Split out as redact_text: an exception is not the only
thing worth returning, and a subprocess's stderr is just as capable of
quoting a token.

calendarList.list returns 100 entries per page by default, caps at 250,
and hands back a nextPageToken when there are more. Reading one page
would have hidden calendars from the picker with nothing to say the list
was cut short. It now pages, asking for 250 at a time, bounded at ten
pages so a malformed token cannot spin.

And a test helper was a lambda where ruff wants a def.

The five new tests fail against the previous commit.

-Endpoint tests for /plugins/authenticate/spotify and .../ytm.
-
-The Spotify step-2 handler writes a Python wrapper script to a temp file
-with the user's redirect URL embedded in it, then runs that file through
-subprocess. That is the most dangerous shape in the blueprint and had no
-tests: the URL is user input reaching generated source code.
-
-The two endpoints are NOT symmetrical, despite the matching names. Only
-Spotify has a two-step flow, a wrapper script, and a redirect_url; YTM
-just runs its script directly.
-
-Regression coverage for one fixed bug: the wrapper file was unlinked in
-the success/failure branch and again in the TimeoutExpired handler, so
-any other failure from subprocess.run — the interpreter missing, a fork
-failure, an interrupted call — left a temp file containing the user's
-redirect URL behind.

-request that has no body at all.
-
-Six handlers in api_v3 read their body as ``request.get_json() or {}``.
-The ``or {}`` states the intent plainly — every field is optional, so a
-bodyless POST should fall back to defaults. But ``get_json()`` without
-``silent=True`` raises ``UnsupportedMediaType`` when the request carries
-no JSON Content-Type, and it raises *before* ``or {}`` is evaluated. Each
-handler's catch-all then turned that into a 500.
-
-So the natural way to call these endpoints — a POST with no body, which
-is what curl, a fetch() without options, and most HTTP clients send by
-default — failed on every one of them. The shipped UI always sends a JSON
-object, which is why this went unnoticed.
-
-This file covers the endpoints whose bodyless behaviour is not already
-tested in their own suite.

-Tests for src/common/logo_helper.py — logo loading, LRU caching, resizing,
-and download-with-fallback. Previously untested: nothing in test/ referenced
-this module at all.
-
-Real PIL images under tmp_path are used rather than mocked ones, since
-load_logo() does real Path.exists() and Image.open() calls; only the HTTP
-session and the permission helpers are patched.
-
-Regression coverage for two fixed bugs:
-- _download_logo wrote response.content to disk with no size cap and no
-  check that the bytes decoded as an image, so a hostile or broken URL
-  could leave arbitrary/oversized content cached in the assets directory.
-- get_cache_stats() divided by self.cache_size unguarded, raising
-  ZeroDivisionError for a helper constructed with cache_size=0.

-"""
-Tests for src/common/sync_manager.py — the UDP leader/follower protocol
-that synchronizes scrolling content across two LED matrix displays.
-
-This module had zero coverage: it only ever appeared in the suite as a
-MagicMock() stand-in (test_vegas_continuous_refresh.py,
-test_display_controller_vegas_tick.py), so none of its real framing,
-handshake, or socket logic was exercised.
-
-Most tests build the manager via object.__new__() + manual attribute
-assignment (the test_display_controller_vegas_tick.py bare-stub pattern)
-so no real sockets open and no background threads start. Receive loops are
-driven synchronously by once_then_stop(): the mocked socket call returns
-one crafted packet, then flips _running False and raises socket.timeout,
-so `while self._running:` exits after exactly one real iteration.
-
-Regression coverage for three fixed bugs:
-- Both recv loops' generic `except Exception` retried with no delay, so a
-  socket stuck raising a non-timeout error spun the thread at 100% CPU.
-- _follower_recv_loop dispatched on `data[:8] == _RAW_MAGIC or
-  len(data) > 512`, which routed any control message over 512 bytes into
-  the image decoder (dropping it) and any raw frame under 512 bytes into
-  the JSON parser.
-- _oversized_frame_warned was read via getattr(self, ..., False) instead of
-  being initialized in __init__.

-dedup_unique_arrays is already covered by test_dedup_unique_arrays.py and
-is not repeated here; this file covers the other eight functions, none of
-which had any tests.
-
-Regression coverage for three fixed bugs:
-- validate_numeric_range accepted True/False, since bool subclasses int.
-- validate_file_upload lowercased the filename's extension but not the
-  caller's allowed_extensions list, so ['.TTF'] rejected 'font.ttf'.
-- validate_image_url only checked for '..' inside the relative-path
-  branch, so http://host/../secret passed validation untouched.
