Add HTTP retry flight definitions to CommonFlight, Fixes AB#3536277

[Copilot]

Adds 6 new flight-gated entries to CommonFlight to enable runtime control of HTTP retry behavior (max attempts, delays, backoff, jitter, Retry-After header respect).

Changes

• common4j/.../flighting/CommonFlight.java — 6 new enum constants appended:

Constant	Flight Key	Default
HTTP_RETRY_MAX_ATTEMPTS	"HttpRetryMaxAttempts"	3
HTTP_RETRY_INITIAL_DELAY_MS	"HttpRetryInitialDelayMs"	1000
HTTP_RETRY_EXTENSION_FACTOR	"HttpRetryExtensionFactor"	2
HTTP_RETRY_JITTER_FACTOR	"HttpRetryJitterFactor"	0.5
HTTP_RETRY_RESPECT_RETRY_AFTER	"HttpRetryRespectRetryAfter"	true
HTTP_RETRY_MAX_TOTAL_DELAY_MS	"HttpRetryMaxTotalDelayMs"	60000

All entries follow the existing CommonFlight(String key, Object defaultValue) constructor pattern. No existing entries were modified. This is a foundational PBI — the retry logic consuming these flights is not included here.

Enum Constant	Flight Name	Type	Default
HTTP_RETRY_MAX_ATTEMPTS	"HttpRetryMaxAttempts"	int	3
HTTP_RETRY_INITIAL_DELAY_MS	"HttpRetryInitialDelayMs"	int	1000
HTTP_RETRY_EXTENSION_FACTOR	"HttpRetryExtensionFactor"	int	2
HTTP_RETRY_JITTER_FACTOR	"HttpRetryJitterFactor"	double	0.5
HTTP_RETRY_RESPECT_RETRY_AFTER	"HttpRetryRespectRetryAfter"	boolean	true
HTTP_RETRY_MAX_TOTAL_DELAY_MS	"HttpRetryMaxTotalDelayMs"	int	60000
