Fixes #28261: [OpenLineage] resolve table identity from symlinks facet (#28360)

* Fix: [OpenLineage] resolve table identity from symlinks facet

* memoize table resolution per event

A dataset is resolved 2-3 times per event (name->fqn map, column lineage,
edge building). Memoize in a per-event LRUCache (cap 1000, reset each
event) so resolution and its warning log run once per dataset. Bounded
and reset every event, so it cannot accumulate or OOM.

* harden symlink facet parsing against malformed events

* restore dotted fallback, scope creation by namespace

* remove entity creation from lineage path

* drop duplicate status warning entries

* align ResolvedTable docstring with read-only resolution

* use raw identities as resolution cache key

* capture database for 3-part dotted names

* fix candidate dedup and column lineage edge cases

* sharpen lineage warnings and harden pipeline fqn lookup

* cover candidate dedup, column lineage edges, and pipeline fqn guard with tests

* bind pipeline_name to a local for basedpyright

* tolerate explicit null in symlink identifier fields

* read context.pipeline via getattr to satisfy basedpyright

* harden malformed-event handling for null namespace and non-dict columnLineage

* make column lineage defensiveness tests non-vacuous

* alias symlink identities in the columnLineage lookup map
