Add ROA Oracle Database Windows setup scripts with old client support

PowerShell scripts for setting up Oracle 21c/XE with ROA application:
- Automated tablespace, user creation and imports
- sqlnet.ora config for Instant Client 11g/ODBC compatibility
- Oracle 21c read-only Home path handling (homes/OraDB21Home1)
- Listener restart + 10G password verifier for legacy auth
- Tested on VM 302 with CONTAFIN_ORACLE schema import

+# Oracle Data Pump Import Parameter File - Company Schema Template
+# =============================================================================
+#
+# Purpose: Template for importing company schemas (FIRMANOUA, COMPANY1, etc.)
+#
+# Usage:
+#   1. Copy this file to import-COMPANYNAME.par
+#   2. Replace COMPANY_NAME with actual schema name
+#   3. Run: impdp system/password@service parfile=import-COMPANYNAME.par
+#
+# Or create dynamically:
+#   $company = "FIRMA1"
+#   (Get-Content import-company.par) -replace 'COMPANY_NAME', $company |
+#     Set-Content "import-$company.par"
+#   impdp system/pass@service parfile="import-$company.par"
+#
+# Prerequisites:
+#   1. DMPDIR directory exists
+#   2. COMPANY_NAME.dmp file is in C:\DMPDIR
+#   3. COMPANY_NAME user created with appropriate tablespace quota
+#
+# =============================================================================
+
+# -----------------------------------------------------------------------------
+# Source and Destination
+# -----------------------------------------------------------------------------
+
+# Oracle directory object containing DMP files
+DIRECTORY=DMPDIR
+
+# Source dump file name
+# IMPORTANT: Replace COMPANY_NAME with actual company name
+DUMPFILE=COMPANY_NAME.dmp
+
+# Import log file (will be created in DMPDIR)
+LOGFILE=import_COMPANY_NAME.log
+
+# -----------------------------------------------------------------------------
+# Schema Configuration
+# -----------------------------------------------------------------------------
+
+# Schema mapping (source:target)
+# Use when source and target schema names are the same
+REMAP_SCHEMA=COMPANY_NAME:COMPANY_NAME
+
+# Alternative: If importing to different schema name
+# REMAP_SCHEMA=OLD_COMPANY:NEW_COMPANY
+
+# -----------------------------------------------------------------------------
+# Import Behavior
+# -----------------------------------------------------------------------------
+
+# Action when table already exists:
+#   SKIP     - Skip existing tables (preserves existing data) - USE FOR MIGRATION
+#   APPEND   - Add rows to existing tables
+#   TRUNCATE - Delete existing rows, then import
+#   REPLACE  - Drop and recreate tables - USE FOR FRESH INSTALL
+TABLE_EXISTS_ACTION=SKIP
+
+# Transform OID to avoid conflicts
+TRANSFORM=OID:N
+
+# -----------------------------------------------------------------------------
+# Performance Settings
+# -----------------------------------------------------------------------------
+
+# Number of parallel worker processes
+PARALLEL=2
+
+# -----------------------------------------------------------------------------
+# Tablespace Remapping
+# -----------------------------------------------------------------------------
+
+# Remap tablespace if source uses different tablespace
+# Common scenario: source uses ROA tablespace, target uses USERS
+# REMAP_TABLESPACE=ROA:USERS
+
+# If source uses multiple tablespaces:
+# REMAP_TABLESPACE=ROA:USERS,ROA2:USERS,SYSTEM:USERS
+
+# -----------------------------------------------------------------------------
+# Exclusions
+# -----------------------------------------------------------------------------
+
+# Exclude statistics (will be recalculated after import)
+EXCLUDE=STATISTICS
+
+# Exclude grants (will be recreated by setup scripts)
+# EXCLUDE=GRANT
+
+# Exclude specific objects
+# EXCLUDE=TABLE:"='TEMP%'"
+# EXCLUDE=INDEX:"='IDX_LOG%'"
+
+# -----------------------------------------------------------------------------
+# Data Filtering (Optional)
+# -----------------------------------------------------------------------------
+
+# Filter specific tables
+# QUERY=TABLEDATA:"WHERE ROWNUM < 1000"
+
+# Include only specific tables
+# INCLUDE=TABLE:"IN ('TABLE1','TABLE2')"
+
+# -----------------------------------------------------------------------------
+# Advanced Options
+# -----------------------------------------------------------------------------
+
+# Skip errors and continue
+# DATA_OPTIONS=SKIP_CONSTRAINT_ERRORS
+
+# Disable logging during import (faster but no recovery)
+# TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y
+
+# =============================================================================
+# Expected Objects in Company Schema:
+#
+# - Tables: gestiune, contabilitate, salarii (~200 tables)
+# - Views: Various reports and lookups (~100 views)
+# - Packages: Business logic packages (~50)
+# - Procedures/Functions: Various (~200)
+# - Triggers: Various (~100)
+# - Indexes: Performance indexes (~500)
+#
+# Total: ~3000+ objects
+# =============================================================================
+
+# =============================================================================
+# Post-Import Steps:
+#
+# 1. Gather statistics:
+#    EXEC DBMS_STATS.GATHER_SCHEMA_STATS('COMPANY_NAME');
+#
+# 2. Recompile invalid objects:
+#    EXEC UTL_RECOMP.RECOMP_SERIAL('COMPANY_NAME');
+#
+# 3. Create public synonym (if needed):
+#    CREATE PUBLIC SYNONYM table_name FOR COMPANY_NAME.table_name;
+#
+# 4. Grant privileges:
+#    GRANT SELECT ON COMPANY_NAME.table_name TO PUBLIC;
