Feat/aoss conditions

[nastya-makarova]

Adds support for conditional logic in Prismarine tables and their triggers, as well as handling of conditions in imported files. Introduces optimizations for AOSS as part of these changes.

[Copilot]

Pull request overview

Adds conditional logic support (!Conditional) to Prismarine table configuration/triggers and to imported easysam.yaml files, with example updates for AOSS conditional enablement.

Changes:

• Resolve !Conditional blocks in root resources.yaml and imported easysam.yaml files before validation/preprocessing.
• Add Prismarine support for conditionally included tables (conditional-tables) and for conditional trigger configuration.
• Update examples (new prismarineconditionals, and conditional gating in example/aoss) and adjust AOSS test expectations.

tables can be None when prismarine_dynamo_tables(...) fails, but the code iterates tables.items() before checking if not tables. This will raise an AttributeError and prevent graceful error accumulation. Move the if not tables: ... continue guard to immediately after the call, before any iteration/use of tables.

This log message concatenates two f-strings without a separating space, producing output like Removing trigger <...>from table <...>. Add a space (or combine into one f-string) to keep logs readable.

Suggested change

	f'Removing trigger {trigger}'
	f'from table {table_name}'
	f'Removing trigger {trigger} from table {table_name}'

New conditional-resolution behavior was added for lists and imported files, but there are no targeted tests asserting list handling and conditional inclusion/exclusion in imported easysam.yaml files. Add unit tests to cover (1) resolve_conditionals with list values and (2) conditional blocks inside imported files to prevent regressions.

The example commands reference example/prismarineconditional, but the directory added in this PR is example/prismarineconditionals (with an “s”). As written, the commands will fail when copy/pasted.

The README claims the conditional table is created in devaoss, prodsam, and stagingsam, but resources.yaml for this example only lists prodsam and stagingsam for conditional-tables. Update either the README or the config so they match.

Suggested change

	- Created only in allowed environments (`devaoss`, `prodsam`, `stagingsam`)

This example module appears to be for the condition package, but it imports common.myobject.prismarine_client and subclasses pc.ItemModel. This will point to the wrong generated client/model. Import the condition client module and subclass the model class corresponding to the Condition table instead.

Suggested change

	import common.myobject.prismarine_client as pc
	class ConditionModel(pc.ItemModel):
	import common.condition.prismarine_client as pc
	class ConditionModel(pc.ConditionModel):
