Respect outside regular hours in fill models

[aiSynergy37]

Description

Updates fill eligibility to respect order-level outside regular trading hours settings when the order properties expose that setting. This prevents extended-hours subscriptions from filling orders that explicitly disallow outside regular trading hours.

The shared exchange-open helper now applies the order property override before checking market hours, and short bars no longer use the large-bar boundary fallback when the exchange is closed at the order time.

Fixes #9476

Motivation and Context

A stop market order submitted during pre-market data could fill when the subscription had extended market hours enabled, even if the order property set OutsideRegularTradingHours = false.

Requires Documentation Change

No

How Has This Been Tested?

• dotnet build Tests\QuantConnect.Tests.csproj --no-restore -v minimal /p:RunAnalyzers=false
• Added a regression test covering both allowed and disallowed outside-regular-hours stop market fills.

Types of Changes

• Bug fix
• Tests

Nice targeted fix. Since this PR routes several fill paths through the new order-aware exchange-open check, the main thing I would want to lock down is coverage across the paths touched by the diff.

Potential extra regression cases:

• OutsideRegularTradingHours = false blocks pre-market and post-market fills for each touched order type: market, stop market, trailing stop, stop limit, limit-if-touched, and limit.
• OutsideRegularTradingHours = true still allows valid extended-hours fills when the subscription has extended-market data, so the new check does not accidentally over-block.
• Unknown/custom OrderProperties types keep the previous subscription-driven fallback behavior.
• Each supported brokerage property class is exercised at least once: Alpaca, IB, Tradier, and TradeStation.
• Boundary timestamps are explicit: one minute before open, market open, market close, and one minute after close.
• A GTC order active across sessions applies the property at fill-evaluation time, not only at submission time.

One related composition check: this should stay separate from engine-generated fills such as delisting liquidations. User-order session constraints should be enforced here, while automatic engine liquidations should not be accidentally blocked by a default OutsideRegularTradingHours = false setting.
