Change some regions to make it work with APEX 19.2

[jeanomobono]

• Verified theme so it's on sync with Vita
• Changed Active Sessions and SGA charts on page 1 with APEX own pie charts (old ones not working on 19.2)
• Changed link icon on reports on page 15 and 17 (changed 'pencil' for 'view')
• Changes primary report filter on page 26, Owner = 'APEX_190200'

I'm currently testing on Oracle XE 18c on my laptop, however my intention is to keep improving it to make it work on a production DB on 11g R2 with APEX 19.2
