feat(samples): [Global Attributes 6] Showcase scope attributes in all sample modules (#5149)

* feat(core): Add scope-level attributes API

Add setAttribute, setAttributes, removeAttribute, and getAttributes
to IScope/IScopes/Sentry so users can set attributes on the scope
that are automatically included in logs and metrics events.

Also refactor type inference logic into SentryAttributeType.inferFrom
and add SentryLogEventAttributeValue.fromAttribute factory method,
removing duplicate getType helpers from LoggerApi and MetricsApi.

* changelog

* ref: Split out LoggerApi/MetricsApi changes for stacked PR

Move factory method extractions (SentryAttributeType.inferFrom,
SentryLogEventAttributeValue.fromAttribute) and LoggerApi/MetricsApi
scope attribute integration to a separate stacked PR.

* feat(core): Wire scope attributes into LoggerApi and MetricsApi

Extract factory methods SentryAttributeType.inferFrom and
SentryLogEventAttributeValue.fromAttribute to reduce duplication.
Apply scope attributes to log and metric events automatically.

* changelog

* feat(samples): Showcase scope attributes in Spring Boot 4 samples

Add Sentry.setAttribute() calls to PersonController and
MetricController across all Spring Boot 4 sample variants to
demonstrate scope attributes being auto-attached to logs and metrics.

Add e2e test assertions and TestHelper methods to verify scope
attributes appear on captured log and metric events.

* test: Add coverage for arrayAttribute factory method

Add arrayAttribute and named array attribute usage to the four
attribute tests in ScopesTest (log, count metric, distribution metric,
gauge metric) to verify the factory method works end-to-end.

* feat(samples): Showcase scope attributes in all sample modules

Add Sentry.setAttribute() calls to all sample source files and
corresponding attribute assertions to all system tests. This extends
the scope attributes showcase from sentry-samples-spring-boot-4 to
all 19 remaining sample modules with system tests.
