fix(510): pin the blank-guard's is-Custom discriminator, verified by mutation
Round-4 review found the fall-through tests, while now falsifiable, still did
not pin the whole guard. Two gaps, both closed and both verified by running the
mutation rather than by asserting the test would catch it:

1. All three fall-through tests used only "   ", so narrowing
   IsNullOrWhiteSpace to `image == "   "` would have passed while breaking
   fall-through for null and "" -- and null is the form the API actually
   persists. Parameterized over null, "" and "   ".

2. Nothing pinned the guard's `ImageSource is Custom` clause. This is the
   sharper of the two: a ChannelLogo watermark's Image is NORMALLY blank
   (the API writes Image = null for every non-Custom source), so dropping the
   discriminator would send every playout-item ChannelLogo watermark down the
   fall-through path instead of resolving the channel's own logo -- with a
   fully green suite. Added
   Blank_Image_ChannelLogo_Playout_Item_Watermark_Should_Win_And_Not_Fall_Through,
   which distinguishes the two levels by watermark Id so a fall-through is
   observable even though both resolve to the same cached path.

Mutation results (each mutation applied on its own, then reverted):

  drop `is Custom` from the guard  -> 1 failure, and the new test is the ONLY
                                      test that catches it
  IsNullOrWhiteSpace -> == "   "   -> the null and "" parameterized cases fail

Negative control re-measured on the final 32-case fixture: 19 fail against the
origin/main resolver. The 13 that pass both ways pin deliberately preserved
behavior plus the positive control, which the record now states explicitly
along with the mutation table.

This round's lesson, recorded in the record: a test's NAME is not evidence it
pins what it claims, and a whole-file revert cannot show that a test aimed at a
specific clause actually reaches that clause -- only mutating the clause can.

Gates: 2661 tests green across 4 projects, 225/225 script tests (the gate I
skipped before the last push), decisions-validate OK, format exit 0, no BOMs.
