fix(media): a number too long to be an episode is not one

The Attack on Titan box set on the array names two files S03E2019 and
S04E47370355, and the provider rows the metadata server recorded for them carry
the same junk. EP_RANGE capped its first episode group at three digits without
guarding the run, so the pass-2 plan filed both under E201 and E473 — slots
that belong to real episodes — inside 進撃の巨人 (2013) [tvdbid-267440].

- guard the first episode group the way the second was already guarded, so a
  longer digit run states no marker at all; a glued resolution stays legal,
  because S01E01-1080p is still ONE episode
- cap a provider row's episode at EP_MAX: such a row is renumbered from tvdb's
  title when the series' id answers, and parks with a reason that names the
  junk when nothing answers
- split the operator-map exceptions into the two things they are: a folder that
  IS on the array whose files never became a series (bonus material with no
  owner: Fairy Tail, Kimetsu no Yaiba, Dorohedoro) is no longer reported as a
  folder the array no longer holds, and the missing-folder hint says the review
  pile counts as moved because the map reads top-level folders only
- the vault's evidence list carries the law; the four tests were read red
  against the shipping planner before any of it changed

Replanning the two real files now parks them under their own names with the
reasons "a provider row of season 3 episode 2019" and
"… season 4 episode 47370355".

 Evidence, strongest first — the order the planner believes things:
 
-- the **episode marker the file's own name states** (`S01E02-E03`, `1x04`);
+- the **episode marker the file's own name states** (`S01E02-E03`, `1x04`); a digit
+  run longer than three at that position is NOT a number — `S03E2019` and
+  `S04E47370355` are one box set's airdate fragment and pack index — so such a file
+  is renumbered by tvdb's title or parks, and is never truncated down to fit;
 - the **`Season NN` folder it sits in and the number its name leads with inside
   it**: `Season 19/01 Charles Barkley, Nirvana.avi` is S19E01;
 - the **provider row**: which episode the file IS, and the numbering of a file
