fix(sports): recover from ESPN rejecting scoreboard date ranges (#591)

* fix(sports): recover from ESPN rejecting scoreboard date ranges

Since 2026-09-15 ESPN's site API answers `dates=YYYYMMDD-YYYYMMDD` with
400 "Failed to get events endpoint." for every sport. Single days, months
(`YYYYMM`) and season years still work. Every season and weeks-window fetch
in core failed, including the background service the scoreboards submit
their season schedules to.

src/common/espn_dates.py re-asks a rejected range as whole-month chunks
plus the leftover edge days, which tile the window exactly (a season is
8 requests, not 213). A month that comes back with exactly 500 events is
truncated (college baseball's March) and is re-asked day by day.

It also clamps `limit` to 500: above that ESPN truncates silently, e.g.
college football returns 25 of 68 games for one Saturday at limit=1000.

BackgroundDataService recovers rejected ranges on the worker thread and
advertises `handles_espn_date_ranges` so plugins can tell whether to hand
it a range. SportsCore, sports_shared, ESPNDataSource and APIHelper route
through the helper or the clamped limit.

* docs(changelog): ESPN date-range fallback and limit clamp

* fix(sports): stop re-sending ESPN date ranges once one is rejected

Live scoreboards refresh every 30 seconds, and each refresh sent the range
first, got the 400, then fetched the chunks: three requests where one used
to do. After a rejection, ranges now go straight to chunks for six hours,
then the range is tried again so the workaround retires itself if ESPN
reverts. A single-day 400 does not set the memo, and when every chunk fails
the range request supplies the error without the chunks being fetched a
second time. Per-fetch chunk logging drops to debug; the rejection itself
stays a warning.

* fix(sports): clamp limit only on ESPN scoreboard submissions

The background service is generic, and limit above 500 only truncates
scoreboards. /teams needs limit=1000 (college football has 762 teams and
limit=500 returns 500), so a teams submission must keep its limit.
