fix(plugin-map): resolve marker titles through getRecordDisplayName

[yinlianghui]

Fixes#5953

ObjectMap was the only one of the four view renderers outside ADR-0079's unified
record display-name resolver. getMapConfig filled an absent title binding with the
string literal 'name', and the marker transform then did a bare record[titleField]
read — so for every object whose display field is not literally name, each marker
popup titled itself undefined. This converges it onto @object-ui/core#getRecordDisplayName,
the same call ObjectKanban.tsx:301, ObjectCalendar.tsx:356 and ObjectGantt.tsx:600
already make.

The change

At the marker read site:

consttitle=getRecordDisplayName(objectSchema,record,{titleField: mapConfig.titleField,fallback: 'Marker',});

The declared binding is passed through as the resolver's explicit titleField
option rather than dropped, so an authored map.titleField still wins outright — the
resolver checks that option first. No authoring surface changes and no new map config
keys: this is a bug fix, not a widening.

Three supporting edits:

1. getMapConfig, flat branch — titleField: schema.titleField || 'name' loses the
   || 'name'. A forged binding is not merely useless, it is harmful: it outranks the
   object's own declared nameField at step 0 of the resolver.
2. getMapConfig, default branch — the same literal, titleField: 'name', removed.
   Bounded in-place fix, declared: the issue names only the flat-branch literal, but
   this is the same literal in the sibling branch of the same function, the same defect
   class, and the correct shape is pinned by the same ADR-0079 evidence. Leaving it would
   have kept the bug alive in a narrower form — a stray name key on a record beating a
   declared nameField. The surrounding coordinate guesses (latitude/longitude/
   location) stay: nothing but this component can read a location out of an
   unconfigured record, whereas a title is precisely what the resolver reads better.
3. objectSchema joins the marker memo's dependency array. It lands from an async
   fetch after first paint, and the titles are now resolved from it; omitting it would
   have left first-painted markers titled from a null object definition permanently.

The pinned test — what its subject actually is

The card flagged that ObjectMap.listViewMapConfigReach.test.tsx "currently pins the
undefined/placeholder behaviour". Measured, it does not. Every one of its six arms
declares titleField: 'title' and asserts a positive title ('Install rooftop unit',
'Bldg A'). The undefined / 'Marker' mention is prose in a comment at line 138,
narrating history — there is no assertion on it anywhere in the file, and a repo-wide
grep for a 'Marker' string assertion returns only that comment and the source line.

So the pin's subject is unambiguously reach — that a declared map block arrives at
getMapConfig and drives the read — and it observes the bug not at all, incidentally or
otherwise. It exercises the one path that was never broken: an authored binding. Nothing
in it is deleted, loosened or touched, and it stays green unchanged.

Placeholders: two competed, one line splits them

Once the resolver arrives it brings its own record-number floor — Record # followed by
the record's id, e.g. Record #77 — alongside this component's 'Marker'. They are
split by whether the record has an id, because that is exactly the split in how much
either can say:

• record has an id → the record-number floor.'Marker' was always weak here — every
  pin on a map is a marker, so the word separates none of them, while the id names
  exactly one record.
• record has no id at all → 'Marker'. Passed as the resolver's declared fallback
  option, displacing its generic 'Untitled', which is the worse word for this surface.

fallback being a declared parameter of getRecordDisplayName, resolving this needed
no change to @object-ui/core — the shared surface the card fenced off.

Tests

New: packages/plugin-map/src/ObjectMap.markerTitle.test.tsx, 7 arms — the flat form
with no titleField (the card's literal symptom), the declared block with no
titleField, the authored-titleField-still-wins invariant, a titleFormat template,
inline value data where no object definition is ever fetched, and the two placeholder
arms.

Reverse-verification. Reverting only ObjectMap.tsx to origin/main and re-running
the file: 6 failed | 1 passed — the direction predicted before the run. The one
survivor is the authored-titleField arm, which is correct: it pins an invariant that
was never broken, not the defect. The mutation was confirmed on disk by anchored greps
in both directions before the run (deleted text restored: 1 hit; injected text gone: 0
hits; the || 'name' literal back: 1 hit), and the restore was trapped on EXIT INT TERM.
No rebuild is involved on this leg: the root vitest.config.mts aliases every
@object-ui/* specifier to that package's src/, so the run resolves source directly
and no dist/ can go stale between legs.

Gates below all ran on 9b93dea with a clean tree.

Lint was run over the whole plugin-map package — the exact unit CI's lint job
covers — not over my three files. The 110 warnings are all pre-existing
no-explicit-any / no-unused-vars across the package's 21 files; the new test file
contributes 7 of them, in the same vi.mock idiom every sibling file in the package uses
(they run 5–12 each), and .github/workflows/lint.yml sets no --max-warnings.
Other packages' lint jobs were left to CI, and that narrowing excludes nothing: the file
population came from eslint's own resolution rather than a hand-written list, the count
of 21 was read from --format json, and eslint.config.js enables no type-aware
linting (no project / projectService in languageOptions), so no rule's verdict on
an untouched file in another package can move as a result of this diff.

The repo-wide pnpm check farm is CI's run, not re-derived here.

Note: an earlier revision of this body spelled the record-number floor with an angle-bracket
placeholder; GitHub's body sanitizer ate the bracketed fragment on write. Respelled above.
