[Master] - Bug 639548 [Expense Agent] Consolidate country demo data into single W1 app (#10637)

## What & why

Consolidates Expense Agent demo data into the W1 demo-data extension
instead of maintaining separate implementations and packages for each
country.

- Introduces a shared country-aware coordinator for setup, master,
transactional, and historical demo data.
- Centralizes country-specific G/L accounts, posting groups, categories,
per-diem rules, expenses, and posted expense reports.
- Supports AT, AU, BE, CA, CH, CZ, DE, DK, ES, FI, FR, GB, IT, NL, NO,
NZ, and US through the same W1 implementation.
- Reduces localization Expense Agent subscribers to the remaining
country-specific integration hooks.
- Removes dependencies on separate country Expense Agent and demo-data
extensions.
- Updates project groups, build configuration, manifests, and object ID
ranges for the consolidated package.

Structured as two commits:
1. Consolidate Expense Agent country demo data into single W1 app - the
consolidation only, no obsoletion.
2. Obsolete the emptied country Expense Agent subscribers (AT, AU, CA,
DE, DK, ES, FR, GB, NZ, US) - wrapped in #if not CLEAN30 and marked
ObsoleteState = Pending with ObsoleteTag = '30.0'.
