R-103: the Tier-2 refusal becomes an action

An app whose Tier-2 copy holds no file legs but a full recovery-unit mirror - 45 of the 53 catalog
templates - was told to press a button on a DIFFERENT page. Since R-102 the data it is asking for is
restorable from the copy it is looking at.

New POST /backup/tier2/unit-restore and backupTier2UnitRestoreHandler: same guards, same
restoreOpBlocked() refusal (R-351b), same async shape as the file restore beside it, plus a
fail-closed pre-flight so the app is never stopped for a mirror that could not be opened. The
outcome reuses unitRestoreOutcomeMsg and adds which copy overwrote the live data.

The row offers the action where the refusal was, in a danger style, as a SEPARATE button. The two
are not merged: one adds what is missing, the other overwrites. The confirm carries that difference
in words and names the copy's date - and says so differently when that date is only an ATTEMPT
(R-101). It is built from named Go constants rather than assembled inside an HTML attribute, so a
test can assert it verbatim; fmtTimeStr now delegates to a package-level fmtRFC3339Local so the
confirm and the outcome cannot render the same date two ways.

tier2NoCoverageMsg is NARROWED to the case that remains - no legs and no openable unit - and still
names the route that works. tier2UnitNotCoveredMsg is NOT deleted: it is appended where the FILE
restore ran and is still exactly true of it.

Tests C1-C2 and D1-D6 plus four more. Red-proofs: C1 (widen CanRestore to include HasUnit -> the
unit-only cases fail), D6 (drop EndRestoreOp from the handler goroutine -> 'the restore never
published a result').

+// Before v0.229.0 an app whose Tier-2 copy held only a recovery unit got a message telling it to
