Task: Rename the curve configuration tables with a _config suffix

Rename the per-entry curve configuration tables so each name says it holds configuration: yield_curve becomes yield_curve_config, fx_volatility becomes fx_volatility_config, and so on. curve_definition, the header row other documents refer to, keeps its name.

• Every per-entry curve configuration table, and its C++ type, repository, protocol, shell commands and permissions, carries the _config suffix.
• curve_definition, the child tables and the tables whose names already say configuration keep their names.
• Every corpus curveconfig.xml still round trips, in memory and through the database.

(Implementation strategy. Written when work starts; key decisions are distilled into the parent story's * Decisions at close, but the plan itself stays — it is the historical record of what we did.)

Every number this task claims about a tree, with the command that produced it and the commit it was measured at. A number without both is not a measurement, because a clean-up record describes a tree and trunk moves under a branch: a consumer count, a gate's component count and a suite's size all change with no code changing, and the reader of a bare number cannot tell which tree it came from. Where the raw output matters, put it in an evidence/ file beside the task and name that file in the Command column.

Manual QA scenarios (scaffolded via compass add test_scenario) that verify this task. Link new ones here as they're created; the scenario doc itself links back via its "Verifies task" field.

The eighteen per-entry curve configuration entities now carry the _config suffix in every layer: table (ores_refdata_yield_curve_configs_tbl), C++ type and repository (yield_curve_config, yield_curve_config_repository), protocol, shell commands, recipes and permission codes. They are the yield, equity, default, inflation, commodity and intraday power curves, securities, the FX, yield, CDS, inflation cap and floor, swaption, cap and floor, equity, commodity and bond future volatilities, and the base and curve correlations. curve_definition, the child tables and the tables whose names already said configuration kept their names.

The rename is reproducible: a script renders the renamed models from the same specs that produced them (the eighteen committed models matched their specs exactly first), removes the 702 files the old names generated, as listed by the generator itself, regenerates, and rewrites the hand-written references in the mapper, its tests and the SQL entry points.

Verified: build clean; database recreated; ctest 90/90, including the whole-document corpus walk and the database round trips.

No migration: on the operator's instruction a database is trashed and recreated rather than migrated, and no backwards compatibility code is kept. The same change removed the thirteen migration scripts this story had added (the curve configuration steps, the report type binding, the stress shift vocabulary and the today's market collection kinds).
