Upgrade Jackson, BC provider, JLine, SnakeYAML, Micrometer and JUnit

[ar-agt]

Summary

Upgrade the dependency groups selected in the dependency review:

Dependency	Previous	Updated
Jackson (core, databind, JSR310, XML)	2.22.1	2.22.2
Bouncy Castle provider	1.85	1.85.2
JLine	4.3.1	4.4.3
SnakeYAML	2.6	2.7
Micrometer core and Prometheus registry	1.17.0	1.17.1
JUnit Jupiter/Platform	6.1.2	6.1.3

Keep bcpg and bcutil at 1.85: 1.85.2 is a provider-only release. Give bcprov its own version and declare it explicitly so both the runtime and published Maven dependency list select the provider patch.

Validation

• Java 26.0.2-amzn and Gradle 9.7.1 selected from .sdkmanrc.
• Clean local test suite: 4,436 tests reported; zero failures/errors, 69 skipped.
• Local jpos:check and jpos:assemble.
• Generated Maven POM and resolved runtime dependencies checked for bcprov 1.85.2, bcpg/bcutil 1.85, and the upgraded library versions.
• git diff --check.

No manual cross-platform interactive-terminal testing performed. JLine 4.4 changes the ambiguous-key binding timeout from 1,000 to 100 ms; SnakeYAML 2.7 removes Compact Object Notation, which is not used in the jPOS source tree.
